Check out this post at Money Saving Mom. It worked for me this morning at CVS on Main.
The Ann Arbor stores don't have any more of the .99 packs, but the one on Industrial does have packs that are $4, which would still make you a couple of bucks. If your store doesn't have these, check for the brand "Sun Covers"... they are reportedly working also.
