I Certainly don't think you ripped me off, I think $150 is a fair price,
Roz Will tell you my sale policy, (I upset enough UK dealers with it in the past

)
I started some of my auctions in the UK at 99p and am letting them run, my US$ ones I set at what I thought was a fair price based on previous auctions but more importantly what I considered fair based on what I pulled out of my cases, I got 3 Bon Bons, so was happy to let 2 go on BINs at $150, the 3rd I put on auction at 99p on the UK Site,
But i must admit I let that one go to an off ebay, the buyer who won my Variant Yellow Weasley Robe was deperate for the Bon Bon Card and the Pepper Imp, and did not want to wait till close of auction so I made a private deal with him, I asked him to name a fair price he would consider paying for them, and he came back and offered me $500 each for the Imp and the Bon Bon, so to be honest greed kicked in and I let them go Was I wrong? I don't think so, I thought that was insanely high, but that was his offer not my request, and he had paid $299 for my variant Robe which was a fair price I think
Anyway I have started to waffle now so I will stop

But No I dont think you ripped me off, I appreciate you took the card you needed and not both, that was the sign of an honest collector
