I received an email from eBay today with the latest eBay Bucks promotion. The Promotion starts at 8:00AM PT on March 27, 2019, and ends at 11:59PM PT on March 28, 2019. During the promotion you earn 2x in eBay Bucks with translates into 4% savings on every qualifying single item of $100 or more.
These offers are targeted and you need to receive the email in order to qualify.
Keep in mind that you don’t earn eBay Bucks when buying eBay gift cards, so the offer should be used to purchase other merchant’s gift cards that you can use later our that can be sold for a profit.
