Note that similar things happen even "off the web." We advertised a small loom and a bass guitar in the local newspaper's free "quick ads" a few months ago. We received about seven identical offers, each for one or the other of the items wanting to send us a money order which we were to cash and forward the shipping fees to an agent (to be identified) who would pick up the items from us.
Can we all spell C.O.U.N.T.E.R.F.E.I.T. M.O.N.E.Y. O.R.D.E.R ?
Referred to local police, but no results reported back to us.
