Here's the thing. Their circular does not come to me in the mail or newspaper. So I look at it online. But what really bugs me is that they put a picture of some item, usually with the size of it concealed, and then say buy 2 get 1 ECB or something similar, but they don't tell you what the price is! So how in the heck can I tell if it's something I want to put on my shopping list?
What I've usually found to be the case is that it's a very small size of the item and the price is ridiculous to start with. So unless I have a high value coupon, it's probably not a good deal.
So for CVS it's usually a good idea to check with one of the experts' sites for what the good deals are...and then double check it yourself. I can often do much better someplace else. That's not to say I haven't got some great deals there, just do your homework.
