I wanted to clarify something about eBay auctions. I just had eBay remove one piece of positive (well, really negative) feedback that implied that the buyer had not gotten what he ordered. This happens because at the time when the buyer is ready to leave feedback, they are presented a potentially REVISED / UPDATED view of the auction. See, I had 2 Seeed green PCBs, and 1 OshPark PCB version to sell. First I sold the 2 Seeed ones. Every time I sold something, I used the old auction as a template and made changes. When I was ready to sell the OshPark PCB, the "DELUXE VERSION", I changed that acution more drastically, by also changing the picture and the heading. And the price is higher of course (90.90 $ instead of 80.80 $). Now THIS has the effect that folks that bought the Seeed version, at feedback time, were presented with a picture and title of the "DELUXE VERSION". Leading them to believe that they had not gotten what the ordered (the 80.80$ version instead of the 90.90$ version!) This is not the case, but a bug in the eBay feedback / auction revision / managment system. So please be aware of that when leaving feedback... check your original "Item Won" message to remind you what you bought, even if the auction has changed in the meantime. Thanks. Only one person got a OshPark PCB for the 80.80 $ price - and that was the first buyer. All subsequent OshPark DELUXE version had to pay 90.90 $.
So, that is a hint for all eBay sellers: CAREFUL with after-sale auction revisions, if you are using them as templates as I did! Don't do it... your buyers will get confused if they haven't kept the original record.
