after bidding for something on ebay and changing your mind is there any way to stop your bid?,had sweat on i bid for dvds only to read after i bid they were in chinese with sub titles,never so glad to be outbid in my life wow.
Retractions are generally frowned on, and reported in your "Feedback as a buyer", BUT unless you make a habit of it it's usually OK - ebay certainly don't investigate the odd one here or there in my experience.
And as earlier response mentioned, just use any of the supplied reason if yours isn't there.
