Guys, I'm not filing a chargeback, or a refund through eBay or Paypal or all that. (The other Best buyers might).
I'm not looking to cause problems for Boomo down the road, I think the auctions were great.
But when the product changes, and people have already bought in, it must be dealt with. The risk was not on my side here, it was on Boomo's. I leave it in his hands to decide how to deal with this and if his decision is screw you, then so be it.
But considering the small take on these 50 auctions compared to his haul as a whole, I feel the right thing to do is simply issue a refund to the 50 buyers, and sell the cards individually. He'll still come out well ahead and the problem is solved.
