Best Buy Coupons, Sales, and Promo Codes

Best Buy offers discounted prices on a selection of products during its Memorial Day Sale. Plus, many items receive free shipping. It matches a similar sale from two weeks ago and is among the best sales we've seen from Best Buy in recent months, yielding several price lows. It includes discounts on computers, HDTVs, cameras, mobile phones, eBook readers, tablets, and more. Sale ends June 1.

At Best Buy, trade in a used, fully-functional mobile phone and receive up to a $360 gift card. That's the largest credit offer we've seen for cell phone trade-ins at Best Buy this year. The credit value will be determined by the condition and model of the phone. As of this writing, a Samsung Galaxy IV (in good condition) will fetch you a $350 credit while an iPhone 5 64GB (in good condition) will yield a $360 credit. (Note, however, that Amazon may offer a slightly higher trade-in credit for the iPhone.) Some conditions may apply.

Best Buy Reward Zone offers 12 points for free when you answer six trivia questions. (You'll need to register your Reward Zone account with Audience Rewards to sign in. Not a Reward Zone member? It's free to join.) That's among the better free points offers we've seen recently, although we saw 25 free points three weeks ago. (For further comparison, we saw 10 free points yesterday.) Allow four to six weeks for these points to apply to your account.

Hint, hint... The answers are "Nederlander Theatre", "She is telekinetic", "Meryl Streep", "Pour Some Sugar on Me", "Covers of existing songs", and "London".

Best Buy offers the HP x4500 Wireless Laser Mouse for $9.99 with free shipping. That's the lowest total price we could find by $13. It features 1600 dpi, a scroll wheel, USB receiver, 2.4GHz wireless connectivity, and Link-5 technology (which lets you connect the mouse to four compatible devices using one receiver).

Update: It's now only available via in-store pickup.
