Free Soda At CVS This Week

This week at CVS, there is an un-advertised ECB deal on Gold Emblem 2 Liter sodas.  The Orange, Grape, Lemon-Lime, and Cola Soda (not the diet) are on sale for $1 and you will get a $1 ECB back when you buy them, making them free.  I believe this is a limit of only 1 per card.
