Check your email if you have a Southwest Credit card, there is a targeted offer for 2x points on gas purchases from August 1st to October 15th. Reading through the terms it states that you must register by October 15th to receive the points and appears it would be retroactive. I have both the Southwest Premier card and the Plus card but only the Premier card worked for me. Check to see if your card was targeted at this link. While double points is nice it isn’t anything that will change my spending. I have better credit cards for gas spending including my Chase Ink credit card that gives me 2x points on gas normally that I can transfer to any ultimate reward partner including Southwest and United Airlines.
However, there are a couple more lucrative offers right now for gas spending. Through Amex Sync you can register for $5 off a $25 purchase at any Exxon or Mobil gas station. That equates to a solid 20% savings. Register all your American Express cards with the tweet #AmexExxon. Another Amex Sync offer that could be used to save money on gas is through Best Buy actually. Tweet #AmexBestBuy and go to your nearest Best Buy and buy some merchant gift cards. At the Best Buy near me there are Shell gift cards and I have also heard of BP gift cards being sold at Best Buy. This equates to 10% savings while not as lucrative and at a higher threshold it is still a good option to save at the pump. Both these offers limit the number of signups and the purchases must be completed by September 30th, 2015.
