Beware of these people. They have a very, very sophisticated scam and a well-done website that looks very legit. They even went through the trouble of creating fake blogs that "review" their services. For example, http://erickjohnpress.org/tag/ahold-safe-transactions/
Apparently, aHold Safe Transactions has been scamming people using different names (eBargainsCo, Alco Safe Transactions, etc.). When things become too evident, they probably just change their name. They use a false address, which turns out to be a public storage facility in California.
My brother in law had an experience that was almost identical to another one reported on this website. He saw an ad on craigslist for a concession trailer. The "seller", Susan Schultz, "lived" in IL in this case (not in Utah). Sadly, he wired them $6,500 dollars as a 50% down payment for the trailer. After that, attempts to contact them have been unsuccessful. They ask for the money to be wired to a bank overseas —that way there is no way of getting the money back.
We too reported them to the FBI. At this point, it has been about two months since the transaction took place and we lost hope of recovering the money. Hopefully this will help other people not to fall into that trap.
