This is YMMV ~ I do not know if eBay offers this to everyone or a subset of their registered users. Good until Saturday 3am eastern (6/17/17), you earn 10% eBay Bucks on your purchases. This time around there is no minimum purchase price per item. Even $1 items earn the bonus. First you have to manually activate the offer from the eBay email or your eBay messages (if invited/selected to participate). Some exclusions apply as usual and the maximum rewards you can earn is $100 per transaction, and $500 during the promotional period.
One great way to take advantage of this promotion is the new condition factory unlocked Samsung Galaxy S8+ (Midnight Black) offered for $700 with free shipping by Samsung’s official eBay store. No contract, no obligation to any carrier, and you can use it on all four major US carriers (Sprint, T-Mobile, AT&T, Verizon) and their assorted sub-carriers (MetroPCS, Cricket, etc) and MVNOs (Page, Republic, TPO, etc). 10% of $700 = $70 in eBay Bucks to be spent in future eBay purchases!
A good place to look for ideas are the eBay Deals along with the Trending Deals (shows only 100 trending deals, less overwhelming to look at than their main deals page). There’s also a dedicated search box there that searches only the Deals, not everything else on eBay.
Another way to look for ideas is our eBay Archive posts.
