Shopping swim stuff on-line

I won't ever buy anything from Metro Swim Shop and I really hope that no one has to go through what I went through. I ordered a swim parka on-line from them and they canceled my order for no apperant reason. After talking to rude customer service and having them told me that my order had been cancel, I ordered another one from swim200 shop. It was great. Three weeks later I got a parka from Metro Swim shop and also find out that they charge my credit card twice. Now I am stuck with two parkas and a bunch of extra charge on my credit card and clueless customer service people on the phone. Did anyone here order from them before? Do you also know a good website to order swimming things??
