Here's how:
  • If you find a qualifying lower price online, call 1-888-BEST BUY and direct a customer service agent to the web site with the lower price, or when visiting a Best Buy store, one of our employees will assist you.
  • On qualifying products, Best Buy will then verify the current price to complete the price match.
