We purchased two totes and have had them for several years, still well prior to the expiration date. They were stored in a cool, dry place.We recently tried one and it was awful. The contents of both totes have been discarded along with the drink mixes. But, hey, we got two sturdy totes out of it, smh. I wonder if dried beans and grains, Mylar bags and oxygen absorbers arent the way to go? User's recommendation: Stay away. Rats wouldn’t eat this stuff.
