I guess the best thing to do is check out both sites before you order something, and figure out from which you can get the best deal once coupons and shipping are figured in. Just a way for a guy to maybe save a couple bucks between two websites that by the looks are actually one in the same. So its not like you are taking your business elsewhere if you really like Tower. I just like to find ways here and there to save a little money that can be put towards more Airplane stuff, and get the most bang for the buck!
