I just paid for my first transaction and just rolled the $5 gift card into 4 split transactions!
Transaction #1 Centrum: buy 2, get $5 gift card. In clearance section 50 percent off, $6.49 ea (reg 12.99) bought 2, used two of $4 off centrum from inserts. Paid $5 for both 120 ct (plus 52 cent tax) got back $5.

I did toothbrushes, then mouth wash as my second then third transaction. Toothbrushes and mouthwash was $4.99 ea, and when you buy 4, get back $5 gift card. I used 30 percent off cartwheel on both, total was around $20 for 4 mouthwash, and $20 for toothbrushes, cartwheel took off $6 on each transaction, then I had four $2 off printable coupons for both transactions taking off an additional $8 on both transactions. Used $5 gift card, and only paid $1.59 for second and third transaction!

Transaction #4 Twin Pack Colgate: $4.79 ea, and when you buy 4 you get back $5 gift card. Total oop at the end including taxes was only 99 cents! That’s 8 tubes of toothpaste for 99 cent!
