10 Tips for Mail Order & Internet Order Success

  1. Always Use a Credit Card
  2. Credit Cards offer the most practical way to enforce your rights.

  3. Get a No-Questions-Asked Money Back Guarantee
  4. Steer Clear of Restocking Fees
  5. Avoid Credit-Card Surcharges
  6. Know the Details of your Service Policy
  7. Determine how your service policy address Parts and Labor on components

  8. Clarify Delivery Terms
  9. Mail-order merchants are obligated to ship products within the time period they specify. If the vendor can’t deliver within that time, it must inform you in writing of the delay and recommit to another date. You have the right to cancel your order if the delay is unacceptable.

  10. Accept No Substitutes
  11. Before you finalize an order, especially on a PC, have the vendor send or fax you a detailed list of components. Don’t settle for a spec sheet that leaves component choices open.

  12. Pay No More Than Advertised
  13. Don’t fall for the classic bait-and-switch scheme, in which a product is advertised at an enticingly low price, but the vendor tells you that it is sold out and pitches a more expensive product.

  14. Get All Sales Terms in Writing
  15. When Things Go Wrong, Get Going

When the vendor won’t cooperate, contact the credit card company. Contact the Better Business Bureau
