Dollar General is not a dollar store. Traditionally a dollar store is a store where everything costs one dollar. Dollar General is a general store that has dollar in the name.
I used to go to the “99¢ Only” store and, let me tell you, everything doesn’t cost 99¢.
Frozen burritos did so I didn’t complain too much.
I once bought a pair of needle nose pliers at the dollar store (actually a dollar) back in the 90s. The first time I used them both the grips immediately bent under a small amount of force, which is actually so funny that I think I got my money's worth in the end.
