I had convinced myself that the two tier ones were all we needed. I changed my mind. We may not keep all three of the two tier ones, but we are definitely keeping these two new ones:
The blue one from above has a removable top layer (shallow, less than an inch deep) and a single compartment interior:
The green one is a single tier with a built in divider and a little fork holder on top:
Very impressed for $1. And I came home with a ton more since I'm shopping for the masses. I think I bought 13 today and only 2 are for us. ;o)
Oh, for those asking which Dollar Trees, I've been to the two in Plano (Alma/15th and Custer/Parker). I know Carrollton is supposed to have them, I'm not sure which others. At the one store, they were in a separate display by the cash register; in the other, they were in the tupperware-like section. Hope that helps!
