Favorite Store?

What is your favorite store to shop at with coupons? Mine is probably CVS, they seem to always have good deals. I got out of Walgreens because it was the farthest for me to drive and my store never seemed to have stock. For some reason, check out always took FOREVER and there were times that the register would not take my coupons and the manager couldn't even get them to push through. It became aggravating so I just avoid it unless there is a really hot deal! I have so many ECB's from CVS, I don't even know what to do with them! I had about 50-60.00 at one time!

Would love to hear your favorite place to coupon :)
