I actually went and looked and the deal isn't bad, but the tanks on sale are the empty "shells" of a tank. The lid and all accessories have to be purchased separately. It's still a good deal if you're buying a larger tank, but if you're getting a 10 gallon its almost cheaper to just get a complete set up. Granted the filter will still need to be replaced, but the hoods to the aquariums when purchased alone might cost a good $20. I have a 29 gallon I gout for 5 dollars, but haven't set it up because of the ridiculous cost on hoods/lights/etc.
