Guess I need to go copy and paste my comment in the Sears thread in this one.
I like Dollar Tree for a number of things. And yes, I bought one of the Dollar Tree $1 3 oz. ribeyes, ate it, and survived. It was a little tough but not too bad. Dollar Tree recently bought out Family Dollar, and existing Family Dollar stores are being remodeled to include "Dollar Tree dollar spots" where you can find some decent buys, although Family Dollar already had a decent section of $1 merchandise.
They are hit and miss, though. I've been in some really nice, clean ones with a decent selection of merchandise. And some look like they're in perpetual tornado cleanup mode.
