Staples is currently offering a $10 instant rebate on $300 Visa gift cards purchased online. The cards normally sell for $308.95 including all fees, however with this discount the total comes to $298.95. There is a limit of 2 discounts per person/transaction.
You do not need any special codes to get this deal. Just visit the Staples site, add 1 or 2 of the cards to your cart and the discount will automatically show up when checking out. I expect there to be a huge demand for these cards since they should earn 5X Ultimate Rewards with Chase Ink or 5% cashback with Amex SimplyCash. This deal may not last long.
The gift cards sold by Staples online are issued by Metabank. For more information on liquidating these cards, see: Beginner’s guide to buying & liquidating Visa & Mastercard gift cards
