Do you save cards?

I'm still working on cleaning out the spare bedroom. Though no one consistently uses the room, we have a dresser in there because it matches the bed. Many of the drawers have gradually been filled over the years and now I'm trying to clean them out . . And I came across two bags of old cards and letters. (I have another bag that I'm currently filling, which made me forget about these two.) I reread them and stirred up lots of good memories. Some went in the trash because they were just plain cards that someone had signed their name to, but I kept all the special ones with a message inside. So I thought - I'll put them in an empty plastic box so they can be stacked neatly in the closet. The only problem is that the containers don't hold nearly as much as I thought they would! I don't think I could possibly toss any more - so tomorrow I'm off to buy another container. Do you save cards?
