I guess when I say TRUE dollar store I mean that every single item in the store costs $1.
I see many places that follow the dollar store concept like the site you gave a link to, where any given person should be able to afford the item. Some items are 89 or 99 cents, other items are $1.39, either way you cut it the merchandise is still cheap and it follows the dollar store concept (maybe in the sense that it all averages out to about a dollar.
Where I live we have like 3 or 4 dollar store concept places, but only one TRUE dollar store. I like that TRUE dollar store place simply because I know that no matter what item I'm interested in, it only costs a dollar.
Where about are you located Johnson?
