Shipping is the leading cause of cart abandonment in Brazil — and the competitor’s free-shipping floor is a public, measurable competitive signal. When they lower the minimum cart from R$ 199 to R$ 99, it shows up on their site right away. The question is: do you react, ignore it or raise yours?
~48%
of cart abandonments cite extra costs (shipping up front) as the main reason for giving up.

Customer obsession is what sustains the shipping decision — but obsession without doing the math turns into a loss.
Why the shipping floor became a battlefield
Free shipping stopped being a courtesy and turned into an acquisition tactic. Because it’s visible and easy to copy, it becomes a race: one lowers the floor, the other follows, and the whole category squeezes its margin at the same time.
What to monitor on the competitor
Floor value
The free-shipping minimum and when it changes.
Regions
Which ZIP codes/regions the free shipping applies to (Southeast? All of Brazil?).
Delivery time
The promised lead time — free but slow vs paid but fast.
Stacking
Whether free shipping stacks with a coupon (combined offer).
3 possible reactions when the competitor lowers the floor
- Match: defensible when your category margin can take it and the SKU is shipping-sensitive.
- Hold and communicate value: keep the floor and highlight delivery time, reliability or a freebie — not every customer trades everything for shipping.
- Raise the floor and win on order value: counterintuitive, but a higher floor can lift the average order value enough to offset the lost conversion.
How much each real off the floor costs
Lowering the floor increases the share of orders where you cover the shipping — and that erodes the residual margin per order. Simulating before reacting is what separates a decision from a bet:
Residual margin by free-shipping floor (illustrative)
Fonte: Didactic example; the reference line is the baseline margin without free shipping (25%).
The Free-Shipping Calculator simulates 7 scenarios with conversion lift and order-value uplift, and points to the floor that preserves most of your margin.

Before vs after reacting with data
Reacting in a panic
- “The competitor zeroed shipping, zero it too!”
- Without looking at the category margin
- Forgets expensive regions (North/Northeast)
Reacting with a break-even point
- Calculates the floor that preserves margin
- Decides by region and by category
- Communicates delivery time/value when it doesn’t match
A shipping surveillance routine
Monitor the rival’s shipping in minutes
Step 1
Check the direct rivals’ floors
Include one Southeast ZIP and one Northeast ZIP in the test.
Step 2
Recalculate your break-even point
How much does their change affect your decision?
Step 3
Decide the reaction
Match, hold and communicate, or raise and win on order value.
Step 4
Communicate it on the site
Keep the floor visible on the product page and in the cart.
Step 5
Measure conversion
Did the change move the order value and the conversion rate?
