I think demand is low and the impact is being felt on values. I have actually sold more on ebay than this forum recently and make okay money on the items that had been lingering around the for sale thread having quite a few viewings but no interest / offers.
Don't know quite what to make of it really as I, on the whole, buy on BC when possible. I know people are feeling the pinch everywhere but things still move, more so in auction formats where people look for bargains and can get a bit carried away with bidding sometimes. The BIN items are the ones to linger - maybe that is the issue on here, prices still a bit high possibly and less room for manoeuvre due to forum rules.
