How much can I expect to pay for an outdoor swing cushion?

Question:I know that I can get the outdoor chair cushions for 20 bucks a piece, but the swing would have to take 3 of them which would be 60 bucks, ouch! Just wondering on that. Thanks!

Answers:
If you have a Big Lots near you, check there. I saw them for $20 (bottom cushion only...no back). Garden Ridge usually has them also, but they're a little more expensive.
