Just so everyone knows I am not affilated with Reptiletubs I have bought from them and there containers are great. Better than Rubbermaid or sterilite. The lids stay shut unlike other products and they don't have all those sharp ridges inside the container. that can hurt a reptile from rubbing.
So you can buy cheaper at walmart or whereever you go, but when your expensive reptiles get loose or injured from cheap containers, well thats just what they are cheap.
