New AMEX Membership Rewards feature: use Rewards to pay for Best Buy online purchases

If you are participating in the American Express Membership Rewards program (different from the Amex Blue Cash rewards), and you also shop at the Best Buy website, there’s now a new feature for you. You can use your AMEX rewards points to pay for a Best Buy website purchase, partially or fully, using your AMEX points.

To do that, enter your AMEX credit card to your Best Buy account (if not already there), and when it is verified and synced (or whatever they need to do in the background), you will see your points and their equivalent dollar value. The e-mail does not say what is the conversion ratio.

It would be nice if it was 1:1, but since they don’t say, one has to wonder. Some promotions, like the Discover-Amazon link offers a 1:1 link, while others, like Citi’s ThankYou-Amazon link is less than 1:1 (not as favorable to the consumer).
