Well, I would say you should in all honesty pay the man.
Hitting buy it now once , ok I believe that, but
hitting Confirm 2nd time, no, sorry, I don't buy that.
THEN if you really don't like it,
you can sell it.
As primarialy a seller, I always put non-payers on a permanent
'no sell to list' on both ebay and all my friends websites.
peace,
