Paypal Digital Gifts via eBay is selling $100 eBay e-gift cards for $95. Unfortunately there is a limit of two e-gift cards per user id.
While eBay gift cards do not earn cashback through portals, you may be able to earn 5X points on this purchase with a Chase Ink card. My purchases from Paypal Digital Gifts as recent as a week ago earned 5X points.
These gift cards are popular since they can be used to purchase other gift cards or merchandise on eBay at a discount. For that reason deals like this tend to sell out fairly quickly.
