American Express has an offer that can save you up to 20% on Best Buy purchases. This Amex Offer was released two weeks ago but today more people are being targeted, and it seems widely available.
Get 2,500 additional Membership Rewards points (or $25 statement credit) one-time by using your enrolled Card to spend a minimum of $250+ in one or more eligible transactions in-store at Best Buy® or online at BestBuy.com® by 9/15/2019.
Valid at any participating location in the US and US Territories. See merchant website for shipping policy. Some merchants may not ship to all areas. Not valid for e-gift card purchases. Excludes corporate gift card purchases. Not valid at outlet locations. Excludes Best Buy Express, Geek Squad services made outside of Best Buy, Best Buy Parts Store, Best Buy Direct, Best Buy Education, Best Buy Ignite, Best Buy Secondary Markets, Best Buy Private Store & Auction or at standalone Pacific Sales stores. Purchases may fall outside of the offer period in some cases due to a delay in merchants submitting transactions to us or if the purchase date differs from the date you made the transaction (for example, the purchase date for online orders may be the shipping date). If American Express does not receive information that identifies your transaction as qualifying for the offer, you will not receive the additional points. For example, your transaction will not qualify if it is not made directly with the merchant. In addition, in most cases, you may not receive the additional Membership Rewards points if your transaction is made with an electronic wallet or through a third party.
Check your cards again and see if you have it. Could come in useful for your Best Buy purchases both online and in stores.
