CVS Deal on 12 packs of Coke Products

I ran by CVS yesterday to return something and scanned my CVS card as usual.  Out popped a coupon for $4/$20.  CVS has 12 packs of Coke products for 4/$10 (limit 8).  I bought 8 packs of Sprite for $20, used the $4/$20, so I got 8 packs of Sprite for $16 + tax!  I haven't seen 12 packs of Cokes for less than $3.33 a pack in a while.
Don't forget to always scan your CVS card when you go.
