Good score on the Ikes. I could never get any ordered, but I have probably searched over 2000 of them found at random banks without finding the first keeper.
I hope not, but getting rid of a consistent thousand(s) of them per week/month may prove to be a challenge. I have no doubt you can sell some on Craigslist and/or eBay for a small profit, but I also think you'll be hard pressed to find a buyer for all of them before the next batch rolls in and they will accumulate quickly. I further think that consistent dumping of loads of Ikes will quite possibly cause dump banks to tire of you quickly.
Good luck!
