If I post a product and the bidding has commenced (one bid) and the reserve is met then I receive a "buy now" offer am I permitted to accept it and close the listing or am I obliged to let the process run its course?  If I accept the buy now offer (in error if that's not permitted) do I just advise the buyer that my acceptance is withdrawn? No preference either way for me - just want to be doing the right (legal) thing.
