CVS is kind of dead this week but this may give you a reason to pop in. You can score 3 free PowerBars. It is a monthly ECB deal.
Buy PowerBar $1.00 (limit 3)
Get a $1.00 ECB
free after ECB
You can buy all three in one transaction and pay $3.00 OOP and get back $3.00 ECB or just buy 1 at a time for only $1.00 OOP and end up with a $1.00 ECB. Whatever works for you.
