eBay problems, resolutions, shenanigans, questions and info (not bike finds)

Fingers crossed - I've forwarded screenshots to PayPal resolution centre showing original sale 3 months ago, the buyer requesting me to send to a different address (than his PayPal one) and royal mail delivery and signature confirmation. I mean - it'll be absurd if he gets his money back. I'd have thought if he hadn't authorised the purchase he may have mentioned it within the last 88 days since he received the item and maybe even returned it!!!
