A coupon isn’t just a discount — it’s a strategic communication artifact. Every public coupon from a competitor carries four vectors of informationthat, read together, reveal what they’re trying to do: acquisition, retention, clearance or defense.
84%
of Brazilian consumers actively look for a coupon before completing an online purchase.

People react more to a loss than to an equivalent gain. A coupon isn’t a gain — it’s the removal of an expected loss.
What a coupon reveals about strategy
A coupon is the most legible offer because it has code, value, condition and expiry — all explicit. The four dimensions that matter:
Code
distribution (public / email / influencer / affiliate)
Value
depth (% or flat R$) and cap/floor
Condition
minimum order, first purchase, category, SKU
Expiry
24h flash vs a week vs structural monthly
Public coupon vs targeted coupon
Public coupon
Where it shows up: banner, Instagram post, ad, microsite.
Who gets it: anyone.
What it signals: acquisition. The competitor wants to win a new customer.
How to react: a counter-offer for your own new customers.
Targeted coupon
Where it shows up: email, push notification, SMS, affiliate.
Who gets it: the existing base, specific segments.
What it signals: retention, reactivation, abandoned cart.
How to react: shield your own base with a loyalty offer.
Frequency, depth and duration — the reading triad
Combining frequency (how many times per month), depth (% discount) and duration (validity window), you get the competitor’s coupon profile:
- Aggressive acquisition: public coupon > 2× per week, high depth (~25%+), short validity (24-72h). Signals pressure for new customers.
- Conservative acquisition: public coupon 1× per month, medium depth (~10-15%), long validity (a week). Signals a controlled media budget.
- Premium/limited supply: public coupon extremely rare (≤1× per quarter). Signals a protected price positioning.
- Recovery: abundant short-duration public coupons + cashback. Signals a revenue target under pressure.
How to map the coupon history
The minimum exercise: a spreadsheet or dashboard with columns for date, code, depth, condition, channel, expiry. Filter by competitor and generate a view of the curve by month.
When a competitor’s coupon is a trap
How to react with your own coupon
Principle: don’t copy, differentiate. Copying hands the competitor the definition of the battle and burns your margin. Differentiating changes the terrain.
Examples of a differentiated counter-offer to a public COUPON30 from a competitor:
- FREE0 above R$ 199 — same perceived value, without passing margin straight through on the SKU.
- Combo “Spend R$ 250, get R$ 50 in credit” — it defers the cost (the ticket rises on today’s purchase, and part of the credit never gets redeemed).
- 15% cashback for returning customers — signals loyalty without lowering the perceived shelf price.
- Extended installments (12× interest-free) — in high-ticket categories (electronics, furniture), it converts better than a flat -30%.
