Payment within 7 days (10 days for non UK buyers). Accepted methods of payment are; Paypal, Cheques (Must be in £ Sterling), UK Postal Order or International Money Order made out in £ Sterling only. If payment is not received within the allotted times, a Non Paying Bidder alert will be issued. This is simply because it is the only way I can recover my Ebay costs.  I ALWAYS obtain a proof of posting certificate.
