I just browse some Coach and Dooney & Bourke purses on ebay and some were really cheap like less than 50 dollars. Also, they were new and looks like the “real” thing..but I don’t know if it is.
Here are some I have looked at Ebay, please check if they are REAL http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEBTOX:IT&item=230226805582&_trksid=p3984.cTODAY.m238.lVI
