Hiya Again,
If you click on "Ended" Items, then you can either click on the "View Confirmation" button (on the same line as your item title) or click on the "Did Not Win".
I've only had 1 (maybe 2?) Did Not Wins and they are both deleted, so I cant tell you exactly what it says...sorry.
The view confirmation shows you a screenshot of when AS placed your bid and the other should tell you exactly what happened and why you got the DNW news.
I would say, drop a line to AS Support and they will tell you ebay didnt accept your bid until too late...it sucks, but it happens...not often thankfully.
Tell your gf that some dumb bugger paid way too much for the item and you can save face until the next one comes along
Thanks for sharing the Auction link, but it doesnt really help as Did Not Win's usually mean that your bid didnt get placed anyways.
