American Express Card Members 5% Cash Back at BP Gas Stations through January 31, 2012

American Express card members can get 5% cash back at BP gas stations through January 31, 2012.

Just register for this AMEX BP 5% Gas Rebate offer to get 5 cents back on every $1 you spend at BP gas stations with your registered American Express card.

Please note that the terms for this offer indicate that you must be the named recipient of this invitation to participate; however, you may be able to register for this promotion even if you didn’t receive the invitation, as I was able to successfully register without having received the email.

You can register any eligible American Express Card by 1/31/2012.

Using your registered Card, you must make a single purchase at any participating location between 12/8/2011 and 1/31/2012.

The reward of 5% will be credited to your registered Card account as a statement credit.

Statement credits are generally issued within 5 business days after your qualifying purchase, but may take up to 2 billing cycles to post to your account.

The registered card number is the only card that can receive the offer, and any other eligible cards (including those linked to the same account) must be registered separately.

The terms are a little confusing, as they indicate that you “must make a single purchase at any participating location,” but the registration page also indicates that you’ll get 5 cents back with every $1 that you spend until January 31, 2012, so it’s not quite clear if the rebate is good on all purchases or a single purchase.

Take advantage of this BP gas station American Express 5% rebate offer when you register your AMEX card today.
