you can get them from Wallmart
btw, this is a pretty cool store for suveniers
http://www.palmettomoononline.com/, there are several around Charleston,. the easiest one to get to is in Summerville(on the way in), its real close to the Dicks Sporting goods if you need any tackle. Its a lot cheaper here than most places downtown. If you are into art, check out this guy
http://www.jimbooth.com/, he's a local, you'll see his stuff all over town. And Guy Harvey has his own resturant(turest trap)here as well.
