Depending on the bedding you are using you can usually get stuff cheaper everywhere else but the petstores. Home depot or a gardening center (target, walmart or nusery) for cypress - most feed stores will carry aspen or there is the newspaper alternative. Flexwatt is cheaper than an UTH and can be bought online, I get my hides and water dished from Reptile Tubs and even shipped they are cheaper than the petstores. Some people have gotten good deals on ebay - but I'd caution that you only get new items - you never know what kind of cooties can be passed on to your collection by re-using someone eleses stuff.
