That is complete nonsense, unless it just happened in the last few weeks. (And most of the action in eBay auctions usually occurs in the last few minutes.)
About a week ago, A500+ Original packaging (opened sadly), plus quite a few games, 5 quid at car boot......Didn't want to carry it....so skipped.....Tandy TRS80 + 4 quid today and again...passed on the opportunity....C64 without PSU didnt even bother asking.
