I have a bunch of heavy duty plastic food grade bins, that can be used for anything. I have not found a load yet that one could not handle. They collapse flat when you are not using them. They are all have the same foot print dimetions (see pictures) but there are several diffrint depths the short ones range form 4-6'' tall. Asking $5 each for the shorter ones and $10 each for the taller ones. call or text me if you have any questions.
