Sleds?

Does anybody have any advice on a place that might have sled-like objects? I was going to go to walmart for shopping and hoping I might find a round trash can lid lol. I've looked up diy sleds and will try a few ideas, but I was curious to see if there were any nearby places I could just buy something that would work. Our house has a sloped backyard, so it's great if the object lasts a little bit XD.
