The promotion generated more orders. It also gave away the shipping, stacked two coupons and taught loyal shoppers to wait until Friday. That is not necessarily a failed promotion, but the sales chart alone cannot decide. Pricing has three jobs: make the offer understandable, respond to demand and preserve economics. This guide starts with the price basis, moves through the mechanics and ends with what the promotion actually changed. Use it before another discount becomes a strategy by default. Examples are illustrative. Advertising rules, reference-price requirements and supplier restrictions depend on the relevant jurisdiction and agreement.

📎 How to read this page
What it means gives the precise meaning. Operator translation gives the version you might hear in a real ecommerce meeting. In real life shows an illustrative example. Watch out and the confusion boxes show where a familiar term can mislead.
📈 Read the relationships first
These combinations are diagnostic hypotheses, not proof of causality. Compare the same period and scope, then investigate the mechanism.
Units ↑ + contribution ↓
Usually means: Volume may be consuming value. Check next: effective discounts, delivery subsidy and incremental basket contribution.
Promotion lift ↑ + following-week sales ↓
Usually means: Demand may have moved forward rather than expanded. Check next: baseline, seasonality and repeat purchases.
Basket value ↑ + shipping subsidy ↑
Usually means: The threshold may encourage useful additions or expensive ones. Check next: the contribution of the extra items.
Price foundations and movement
01 · 🟢 Core
Markup
🧠 What it means
The amount added to a product's cost to set its selling price, expressed in currency or as a percentage of cost. It answers a different question from margin, which uses selling revenue as its denominator.
💬 OPERATOR TRANSLATION
“The percentage we put on top, which finance keeps reminding us is not the percentage we keep.”
🛍️ In real life
A $40 product sold for $60 has $20 markup, or 50% of cost.
🧮 Formula
(Price − cost) ÷ cost × 100. The same example has a 33.3% margin before other costs.

MSRP/RRP = Suggested retail price
🧠 What it means
A manufacturer's recommended consumer selling price. It is a recommendation, not proof that customers commonly pay it or that a retailer must charge it; legal and contractual restrictions depend on the market.
💬 OPERATOR TRANSLATION
“The price the manufacturer would like us all to believe in.”
🛍️ In real life
A supplier suggests $80 for a kettle while a retailer sets its actual selling price at $70.
⚠️ Watch out
A suggested price alone does not justify a misleading discount comparison.

MAP = Minimum advertised price
🧠 What it means
A supplier policy concerning the lowest price a reseller may advertise, typically associated with US distribution arrangements. It concerns advertising rather than necessarily the completed transaction price; enforceability and competition-law treatment depend on jurisdiction and design.
💬 OPERATOR TRANSLATION
“The price we may shout, which is not automatically the price we may quietly accept.”
🛍️ In real life
A US brand's policy sets an advertised floor for dealers; the merchant checks its actual contract before promoting a discount.
⚠️ Watch out
Do not assume a US policy is lawful or applicable in another country.

Reference price
🧠 What it means
The comparison price against which an offer is presented or evaluated, such as a genuine former selling price or a stated recommended price. Its basis and lookback requirements depend on local consumer-protection rules.
💬 OPERATOR TRANSLATION
“The crossed-out number that needs a history, not just a designer.”
🛍️ In real life
A store labels a genuine prior price separately from today's sale price and retains the pricing records.
⚠️ Watch out
In the EU, announced reductions generally reference the lowest prior price over the relevant 30-day period, with exceptions.

Price elasticity
🧠 What it means
The responsiveness of quantity demanded to a price change, usually measured as percentage change in quantity divided by percentage change in price. Estimates require a stated method and comparable conditions; a promotion alone rarely isolates price.
💬 OPERATOR TRANSLATION
“How loudly shoppers vote with their feet when we change the tag.”
🛍️ In real life
Using simple percentage changes, a 10% price rise and 15% quantity decline gives elasticity −1.5, assuming other factors are held comparable.
⚠️ Watch out
Product mix, seasonality and advertising can distort an apparent price response.

Dynamic pricing
🧠 What it means
Changing prices in response to inputs such as demand, inventory, time or market conditions. The rules may be automated or manual, and the practice is not synonymous with charging every shopper a personalized price.
💬 OPERATOR TRANSLATION
“The price has a schedule; hopefully someone told the support team.”
🛍️ In real life
A merchant reduces a perishable product's price as its sell-by date approaches.

Repricing
🧠 What it means
Revising an existing selling price, often using software and competitive signals to manage marketplace offers. Rules may include floor prices and margin constraints; lowering the price is only one possible outcome.
💬 OPERATOR TRANSLATION
“The competitor moved a number, and now our number wants a meeting.”
🛍️ In real life
A seller's repricer raises its offer when a rival goes out of stock, while respecting a defined floor.
⚠️ Watch out
Fees and cost changes can make yesterday's floor unprofitable today.

Price parity
🧠 What it means
Keeping or requiring equivalent prices across specified channels or counterparties. Its meaning depends on which prices, fees, products and dates are compared; contractual parity clauses and legal treatment vary by market.
💬 OPERATOR TRANSLATION
“Our website and marketplace tags are trying not to start a family argument.”
🛍️ In real life
A brand compares the same SKU's publicly offered price on its website and marketplace, allowing for shipping differences.

Markdown
🧠 What it means
A reduction from a product's previous selling price, commonly used to clear stock or respond to demand. It can be temporary or lasting and is a pricing action, not a synonym for every form of promotion.
💬 OPERATOR TRANSLATION
“The warehouse asked politely; now the price is asking more loudly.”
🛍️ In real life
A retailer reduces end-of-season jackets from $100 to $70 to clear remaining sizes.

Loss leader
🧠 What it means
An item deliberately priced at a loss, on a stated cost basis, to attract shoppers or support profitable purchases elsewhere. The strategy only works if the wider basket or customer economics justify the sacrificed contribution.
💬 OPERATOR TRANSLATION
“This item loses money; the plan is that the rest of the basket has manners.”
🛍️ In real life
A retailer sells a staple below its acquisition cost, expecting shoppers to add profitable complementary goods.
⚠️ Watch out
Basket economics and local restrictions matter; footfall alone does not cover the loss.

Bundle pricing
🧠 What it means
Setting a combined price for multiple products or services. The bundle price can be below or equal to separate prices; pricing belongs here, while the merchandising act of assembling the offer is a separate decision.
💬 OPERATOR TRANSLATION
“Three items share a price tag, and hopefully share a margin calculation.”
🛍️ In real life
Products priced separately at $20 and $30 are offered together for $45.

Volume discount
🧠 What it means
A lower price or discount conditional on purchasing a specified quantity or volume. It may apply to all units or only units beyond a threshold, so tier mechanics and returns treatment need to be explicit.
💬 OPERATOR TRANSLATION
“Buy more, pay less per unit, then explain the difference to the warehouse.”
🛍️ In real life
A merchant offers 10 units at $9 each versus one unit at $10; all 10 units receive the tier price.

BOGO = Buy one, get one
🧠 What it means
A promotional mechanic linking a qualifying purchase to another item free or at a specified discount. The products, quantities and eligibility rules determine the actual benefit; the abbreviation alone does not tell the full offer.
💬 OPERATOR TRANSLATION
“The second item is invited, but someone still pays for making and shipping it.”
🛍️ In real life
Buy one $20 item and receive an eligible second item free; product costs apply to both.
⚠️ Watch out
Buy one, get one half-price is not the same offer as a free second unit.

GWP = Gift with purchase
🧠 What it means
A free or included item offered when a shopper meets defined purchase conditions. The gift can encourage conversion or basket growth, but its cost, availability and perceived value still affect promotion economics.
💬 OPERATOR TRANSLATION
“A little present from us, financed by a very unromantic spreadsheet.”
🛍️ In real life
A beauty store includes a sample kit with orders above $60 while supplies last.

Coupon stacking
🧠 What it means
Applying more than one discount or promotion to the same purchase where eligibility and combination rules allow it. Percentage discounts may apply sequentially rather than being added, so the effective reduction needs calculation.
💬 OPERATOR TRANSLATION
“Two codes walked into checkout; margin hoped one would be turned away.”
🛍️ In real life
Sequential 10% and 20% discounts on $100 produce $72, a 28% reduction rather than 30%.
🧮 Formula
$100 × 0.90 × 0.80 = $72. Check tax, shipping and combination rules.

Free-shipping threshold
🧠 What it means
The qualifying basket value above which the merchant waives a stated shipping charge. Define whether qualification uses value before or after discounts, taxes and exclusions; the merchant still incurs delivery costs.
💬 OPERATOR TRANSLATION
“The line that convinces shoppers to buy a candle to avoid paying for a box.”
🛍️ In real life
A store waives standard shipping when eligible items total $75 after discounts.
⚠️ Watch out
Added basket contribution should cover the shipping subsidy; revenue alone cannot tell you.

What the promotion changed
17 · 🔵 Operations
Promotional cannibalization
🧠 What it means
A promotion shifting purchases away from another product, channel or future full-price sale, rather than adding entirely new demand. Observed sales may still rise even while the overall business sacrifices margin.
💬 OPERATOR TRANSLATION
“We sold more today by borrowing tomorrow's orders and discounting yesterday's loyal customers.”
🛍️ In real life
A discounted large pack replaces purchases of two full-price small packs that would otherwise have occurred.
🔗 Related: Promotion lift · ↑ all terms
18 · 🔵 Operations
Promotion lift
🧠 What it means
The change in a chosen sales outcome relative to a defined baseline during a promotion. Observed lift is descriptive; a causal incrementality claim needs a credible counterfactual that addresses seasonality, other activity and cannibalization.
💬 OPERATOR TRANSLATION
“The sale got louder; now prove the extra noise brought extra buyers.”
🛍️ In real life
Promoted units of 150 versus a 100-unit baseline show 50% observed unit lift; that comparison alone does not prove causality.
⚠️ Watch out
State the outcome, baseline and period. Revenue, units and contribution lift can disagree.
🔗 Related: Promotional cannibalization · ↑ all terms
🔀 Markup vs margin
Markup divides the price-minus-cost gap by cost. Gross margin divides gross profit by revenue. A $40 cost and $60 price gives 50% markup, not 50% margin.
🔀 MSRP/RRP vs MAP vs reference price
A suggested price, an advertising policy and a comparison basis serve different purposes. None makes an unsupported discount claim true.
🔀 Bundle pricing vs volume discount vs BOGO
A combined offer, a quantity tier and a conditional second-item benefit have different eligibility and cost mechanics.
🔀 Observed lift vs incremental demand
A sales increase against a baseline describes a comparison. Proving additional demand caused by the offer requires a credible counterfactual.
