I would say of late individual cases on ebay were going for between $.75 - 1.00. I was willing to pay $15 for 20 and $25+ for 40ish.  Got outbid on both.  So finally this huge lot of 96 turns up and I bid $60 thinking maybe no one else would want to spend that much.  Turns out I won the whole thing for $16.25.  I'm still waiting for something bad to happen...
