CDs (almost) any condition, for school project

Class project needs about 200 CDs - either music or data is fine,
unplayable/scratched is fine, but not terribly cracked please - they are
going to be wheels so they need to be round and sturdy. Cases not needed
but if you want to get rid of cases too that's fine!Happy to pick them
up at your convenience. Bigger batches preferred if possible, I hope I
can get more than a couple at a time :) Thank you!
