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 Low Price 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.

Why don't we show the price?

As a retailer, we set our own prices independently, but some manufacturers restrict how we may communicate those prices. In some cases the manufacturer does not allow us to show you our price until you take further action. Don't worry; you can remove the item from your cart if you decide not to buy it.

To see the price:
Add the items to your cart and then click check out.
