Just like with any site, company or individual, always be cautious. Anyone buy or selling needs to understand to cover all the details. I've been taken by reputable companies as well. Don't think there aren't scam artists in every situation, both sellers and buyers. I recommend the golden rule of educate yourself on the details and sequence of a sale first, always get documentation as a CYA and stick to your requirements as to payment methods. Don't be in a rush to do the deal, part with your goods or money. There is always another boat out there or another customer. If it is meant to be it will be.
