Price Match Guarantee

Best Buy is dedicated to always offering the best value to our customers. We will match the price, at the time of purchase, on a Price Match Guarantee product if you find the same item at a lower price at a Designated Major Online Retailer or at a local retail competitor's store.

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.

Some exclusions apply. See the list of Designated Major Online Retailers and full details.
