Post-Carnival 2026: What Changed in E-commerce Margins

Carnival moved little in volume, but a lot in competitive behavior. The month’s read.

Post-Carnival 2026 confirmed what was already on the radar: the stretch between Back-to-School and Mother’s Day is the narrowest competitive window of the year, yet paradoxically the moment when competitors most test new structural mechanics without the noise of the big dates.

average coupon depth in Feb/Mar 2026 vs Feb/Mar 2025.

The transition period

Between Carnival and Easter, Brazilian e-commerce enters a transition phase:

  • Back-to-School has wrapped up (the long-tail clearance ends in mid-February).
  • Easter doesn’t yet weigh on every category (it concentrates in food, chocolate, fragrances).
  • Competitive behavior normalizes — deep coupons disappear, brand goes back to talking about brand.

What mattered in 2026

-14%

drop in average depth vs the prior year

+38%

increase in institutional communication (brand, values, purpose)

~28%

of brands tested a segmented coupon (new vs returning audience)

63%

of stores with a Q2 launch announced in March

Early signals for Mother’s Day

Whoever tested a segmented coupon (new vs returning audience) in February/March will likely scale the mechanic in May. It’s worth mapping which competitors experimented — those will be the hardest to predict in the Mother’s Day campaign.

Key competitors to watch:

  • Who ran a coupon A/B test on Instagram.
  • Who activated cross-channel communication without high depth (testing reach).
  • Who announced a product launch for May in their March communication.

Operational recommendation

Use March to calibrate process, not to react:

  1. Clean up public sources — sources inactive for > 30 days have probably changed URL or been discontinued.
  2. Update the priority list — who grew vs who regressed in Jan/Feb?
  3. Generate an executive PDF for Jan/Feb for the board meeting. A consolidated read serves as a baseline.
  4. Prepare the Mother’s Day playbook 4-6 weeks in advance.
