CVS trip (35.53% savings)

I decided to give CVS a try since they have an awesome deal on Pepsi products this week. I bought 6 12 packs of diet pepsi. The shelf price is $33.04. The sales price is 6/$20. When you buy 6, you get $10 ECB. This is like paying $1.67 each!! That is an amazing deal! If you don't work the ECBs in (since I had none to use on this transaction- you have to start somewhere), my savings were 35.53%.
