I used a company called, escrow.com a few months back. Bought a '41 ford pick up as a gift for an employee (long story). Had it shipped from Colorado to California and everything from my end worked just fine. But the seller, had issues receiving the funds.
Escrow.com wired the money to the wrong account and didn't do anything to fix the situation. My bank and the sellers bank tried to work things out. But ultimately, the seller got the federal government fraud division involved. It's been several months, and I don't know if anything has been resolved yet.
Long story short: Don't use escrow.com.
