Many sites offer a profile of sellers based on comments from other buyers.
Be aware that positive comments could be planted by the seller. If it's a business, contact your local or state consumer protection agency and the Better Business Bureau for more information about it. For sellers, know the buyer. Check feedback to see if he or she provides payment on time. Know the product.
