Cashback vs coupon discounts
A coupon usually reduces the price at checkout. Cashback usually gives money back later through a cashback provider, card program, or affiliate reward. That means cashback may improve your effective savings without lowering the checkout total immediately.
Example
If your order is $100 and you use a 10% coupon, your subtotal becomes $90. If you also receive 5% cashback on the eligible amount, your estimated cashback is $4.50.
