I've got over 40 of those [from dollarama too!].
I use them to transport herps, as well as display cases when we do shows and stuff.
They are handier than delis for selling as they come with a handle and are nicely vented.
my "care packages" for herps I sell, include one of them, plus a caresheet, business card, substrate, and some mealies for the insectivores.
