FAQ
Is a 20% discount the same as lowering R$20?
No. Percentage is proportional to the original price. In R$100, 20% = R$20; in R$350, 20% = R$70.
How to calculate discount with coupon and promotion together?
Apply in the order informed (sometimes it is a percentage and then a fixed value). If you don't know, simulate the two orders and compare.
Why does the final price sometimes not match the store?
There may be rounding, cent rules, shipping, fees or a discount applied at a price different from that advertised.
