Item (Football hat) listed on Simple Delivery to UK; GSP open for international buys. Ordered from Australia but GSP appears not to be working or will not send to Australia. I'll send anywhere! His eBay agent advises I can send an invoice with postage costs to Australia BUT, as listed under Simple Delivery (no choice), sellers cannot send invoices as eBay responsible for all postage issues. I've used the Exempts link to ensure buyer is not blocked. SO we're both stuck - he wants to pay/I want to send by GSP - HELP! Any advice appreciated.
