I'm not sure whether this is the right board to ask, but I'd really like to find a small, inexpensive slide for my 3yr old Dd. Whether it's the kind that comes with swings or not doesn't matter. Wal-mart used to sell those little orange and blue plastic slides, but not anymore. Are there any stores where you've noticed smaller plastic slides?
Seems like slides & bikes are things you often see at garage sales, too. Now that garage sale season is coming up, you could try that, if you have the time to spend a Saturday morning or two (or three!) driving around your neighborhood.
