i checked, but i don't think anyone has posted this website yet. if someone notices that it already has been just let me know.
I just found the cheapest website for reptile stuff. They don't carry a ton of turtle stuff just yet, however they do have the cheapest prices you'll find anywhere, and if you find it cheaper somewhere else, just let them know and they'll lower it!

i even work at a pet store and get a lot of stuff free from there, but we don't sell much in the way of reptile stuff so i know i'll be shopping at this website for a while.
