It will allow you to earn 2% cash back on gas purchases and on purchases at restaurants. Once these purchases reach $1,000 cap in a given quarter, your cash back will be lowered to a regular 1%. All other purchases will earn 1% cash back without caps or limitations. Also, if you have a balance on your Shell card, you will be able to transfer it to the Discover it® Chrome-Double Cash Back your first year and pay off at 0% intro APR. You will have 12 months to pay off a transferred balance.
