Keep Records.

What documents should you keep when purchasing online?

• A printout of the web pages indicating the seller's name, postal address, and telephone number;
• A printout of the web pages describing the item(s) that you ordered;
• A printout of the web pages or pop-up screens that provide the seller's legal terms;
• Printouts of any e-mail messages (for example, confirmation messages) that you send to or receive from the seller. This includes:
  • Those that might show that the seller indicated that the product would be suitable for the specific purpose for which you needed it,
  • Those in which you notify the seller of problems with the merchandise that you have received; and
  • Those that would show your good faith attempt to resolve with the merchant a charge that you do not feel should have been made to your credit card.
• Notes or e-mail confirmations of any telephone conversations that you have with the seller.
