They are not currently the highest bidder but I didn't even realise people could hide their feedback. I'm not comfortable with it can i remove their bid? (They may be perfectly genuine but tbh I can't be bothered with the potential hassle if they turn out to be a pain in the arse)
I already feel as a seller the cards are stacked against you these days with eBay so although it might be unreasonable I feel a bit picky about my buyers! Maybe they buy a lot of "well worn" items and want to protect themselves but in that case get a separate eBay account for the time you want to buy a doll's house!
