Staples Mastercard Gift Card Rebate Deal I love me some Staples gift card deals. Following a longish drought, they have a Visa gift card deal running this week and are going to follow it up with a Mastercard deal next week. Let’s take a look at the details of the new offer since it is a bit different. The Deal Buy $300 of MasterCard® Gift Cards and get a $20 Staples® Gift Card after easy rebate. Key Terms Valid 3/20/16–3/26/16. Limit 1 per customer. (This normally reads one per household. It will be interesting to see how the rebate form is worded.) In store only.
