Seems to be a repeat scammer. The name Bark40oz links to the name Will Henley, DOB April 12 1980
here. Location Colorado, also
here.
A Will henley is reported as a scammer
here and the reporter also leaves a mailing address (or part of one) - seems the person also goes by some other names (Aaron Lewis, Keith Buff).
Could all be made up names, but keep digging and linking the details: you're bound to find some decent contact details for him/her.
Hope you get your cash back.
Regards
Rich
EDIT: it seems some other people on the last site I linked to (Neo-Geo.com) are really pi55ed off with this guy, and have his mailing address details (the user provile gives the same DOB as the user profile linking the names "Will Henley" and "Bark40oz") - it's probably worth PMing the people on that site to try to get more details.
