I bought a skateboard at a different shop (not Ground Zero) and it didn't seem to work right. I hadn't noticed until the lady at Ground Zero pointed out that one of the trucks was on backwards. They fixed it for free. While I was there I noticed it would have been cheaper at Ground Zero.
I go here a lot, now, and they always have the newest stuff as far as shoes and decks goes. They also have clothing brands that are hard to find and they have good prices. I also like that they are always really friendly.
