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?
Sounds likea great idea, though I don't know why since your questions were answered by sojo.
The exclamation point is to report someone's post. If someone were to be overly hostile and post maybe using threatening or vulgar language, you would report them to the moderator to have it edited or removed. If someone posts about politics or breaks forum rules (such as naming the client and the MSC in the same thread) you might report it to the moderator.
