ping pong balls needed

[tassis]

I'm wondering if any of you crafty ladies know where I can get lots of pingpong balls cheap. For craft/game thing at a church holiday club, not for table tennis.

Any ideas?

somebody...please

i bought polystyrene balls and they've just been rejected so I NEED an alternative.

they sell lots of them on ebay? or a sports shop?

Ebay of course!
