Office Depot and OfficeMax have launched a returning promotion on Mastercard gift cards, allowing customers to save $15 instantly for every $300 spent. This deal provides a valuable opportunity for buyers to reduce costs when purchasing multiple gift cards. Customers can purchase up to ten cards per household or business, but individual store policies may vary, potentially imposing stricter limits. The discount applies in increments of $300, so buying three cards totals $600 and triggers a $30 discount. This strategy maximizes savings by stacking the discount for every $300 increment spent. A practical approach for maximizing value involves buying gift cards in sets of three. Although each card carries a purchase fee of $7.95, the $15 discount per $300 results in an effective net gain. For instance, acquiring three cards will yield a net profit along with possible additional rewards from credit cards or loyalty programs. Larger purchases, such as nine cards, amplify potential savings and rewards but may require an ID check to verify the payment source. This offer is valid for a limited period, running from early May to mid-May. Office Depot and OfficeMax have consistently provided similar promotions in past months, making this a recurring chance for consumers to benefit from discounts on prepaid Mastercard gift cards. Buyers should keep in mind the timing of the promotion and their store's specific policies, as availability and purchase limits may differ by location. Taking advantage of the deal through calculated increments can optimize savings while minimizing fees.
