I have a pretty rare 3rd shirt from 2002/03 on eBay - http://www.ebay.co.uk/itm/281628772273? ... 1555.l2649
They didn't sell many as it was the same shirt as the previous season's away, just with O2 instead of Sega.
I have loads of others that aren't on eBay as I'm clearing out my collection to make more room for goalkeeper shirts (http://www.arsenalgkshirts.co.uk)
