While MS for a Hallmark Brand store for greeting cards seems harder. I would assume all other stores selling greeting cards could be Joe Bow greeting cards. The store brand ---Dollar Express-- is already telling you that very few items in the store is more than a "Dollar". The store Dollar Express is not a HallmarkBrand store, which is over-rated when it comes to cards anyway.
Greeting cards, I have seen in DE are generally, 2 for $, $2 for some, and perhaps a $3 card for others. I rarely have seem a card cost more. Basically any occasion cards.
So I ask You---OP----what kind of cards are you looking for or what kind of cards are you asking to audit?
