For example Garnier Fructis are on sale at Target plus you will get a $5 GC. But to make a deal a better one. You could find a coupon to lower your out of pocket
If you buy 4 Garnier Fructis @ $2.99= $11.96 Use (4) $1/1 MQ on Sunday paper= $7.96. You will receive a $5 gift card After GC is $2.96, .74 each
Another example and easier one are the BOGO like Publix. Buy one Sambazon $2.79 and get one free. You are able to use 2 coupons. As you could see the item has a .55 cent hangtang.
You buy 2 items for the price of one $2.79- 1.10 = $1.69. Making them .84 cents each.
