From 4/7/2019 to 4/13/2019, Staples is running a promotion on several third party gift cards. Some of these brands, such as Petco for example, could be useful for reselling and earning tons of Chase Ultimate Rewards if you have a Chase Ink Plus/Cash credit card. What was great about the offer is that there was no limits stated in the ad. But now Staples has once again added limits in store with a notification from corporate, just like they did with a previous gift card deal last month.
The limits posted in stores, state that you are now allowed to purchase only 10 gift cards. They also apologize for the inconvenience. The limit might not matter to most people as many Staples stores are already out of stock on the eligible cards.
