How is there such a huge market for cards that it takes up an entire aisle or even two at some stores??
There isn't, really. Hallmark lays off more workers every year. They've closed at least one plant completely, probably more. Any time a store renovates, it allocates less space to cards.
My stepmom is really into Hallmark, though. She's always sending out these beautiful, expensive cards for every occasion and holiday. I feel kind of bad when I throw them in the recycling.
Personally, I get a lot of free cards from a couple of animal/wildlife organizations.
I once had someone comment on it, "Oh, I saw the card you sent me was a free gift from X organization. A little cheap, don't you think?"
I didn't send her any more cards.
