1This offer is for select cardmembers and is not transferable. If your account is closed or you switch to another product during the promotional period, you may no longer be eligible for this promotion. If you receive this offer and enroll by 8/26/21 you will earn 3 additional miles for every one dollar ($1) spent on grocery store, drug store and restaurant purchases, less credits, returns and adjustments ("Net Purchases") with transaction dates between 8/1/21 through 10/31/21, up to a maximum of $500 in spend in these categories each month. The maximum earn for this offer is 4,500 miles. Purchases in the specified reward categories must be submitted by merchants using the corresponding Merchant Category Codes (“MCCs”) in order to earn additional miles. MCCs are categories used by merchants based on the goods and services they sell. Barclays uses the MCCs when creating the reward categories however, we have no control over how merchants choose to be categorized and as a result, some purchases may not fall into the expected rewards category and will not qualify to earn additional miles. Additional miles may not be earned if the merchant submits the purchase using a mobile or wireless card reader or if you use a mobile or digital wallet to pay for the purchase. Additionally, purchases made through third parties, including online marketplaces and resellers, or using a third-party payment account, will not earn additional miles. Failure to maintain your creditworthiness during the offer period may result in actions on your account, such as a credit line decrease, that would reduce your ability to take advantage of this offer. To receive the additional miles, your account must be open, active and in good standing at the time of fulfillment. All miles earned from this promotion will appear on your statement 6-8 weeks after the end of the promotion.
