Paypal Digital Gifts via eBay is selling $100 eBay eGift cards for $95. There is a limit of 1 per user id. These deals normally sell out quickly.
While eBay gift cards are generally excluded from portal cashback (some people report success despite the terms), you may be able to earn 5X points on this purchase with a Chase Ink card and could try to go through Inbox Dollars for 5% more.
These gift cards are popular since they can be used to purchase other gift cards or merchandise on eBay at a discount.
