When a bigger amount is involved, I always use Escrow. In other words, any transactions involving $100 or more will have me use Escrow. I use Escrow as a seller as well as a buyer. When I want to buy I send funds to escrow so that the seller does not cheat me. And when I sell, I ask the buyer to deposit funds in Escrow before I deliver the product or service. Do you use Escrow?
