Hey guys just for info when you want to buy expensive goods such as a Rolex
1) The website should guarantee the security of your transaction from beginning to end. The user navigates through a website protected by an SSL certificate.
2) The website should guarantee that the buyer receives the requested watch and the seller receives the payment. The watch should also be checked by a team of experts to ensure the authenticity of the product.
3) The payment is ensured. The watch is collected once the website has received the buyer’s payment. Never before...
4) The seller knows the amount they will receive from the moment the item is published for sale.
5) To be sure that the buyer is satisfied, the payment is released once the 14 days return period has passed.
6) The website should provide a warranty that gives the customer security over the following 12 months.
I found this info on one of the websites that sell second hand luxury watches
