Yes, because it's a pain finding people who will take them. I only have room for about 125 of them, and I don't like having them on the floor.
Though in truth, there are only a few I regret buying - most of them I had a good reason I bought them at the time (like they were part of a larger purchase, or came with a cabinet or accessories that made it a good deal). I just have more than I have space for.
