I have three people living in a one-bedroom apartment - the last thing we have is a lot of space for card displays. I only own a single uncut sheet and don't plan on getting more. And as said before me, they could be very nice, and even given out for free, but the shipping charges would make it prohibitively expensive.
Perhaps they should focus more on actually getting decks in the mail and to their buyers... The last time I looked, they weren't in the jewelry or furniture businesses...
