eBay rotates these type of offers, so they typically only cover a percentage of the participants in the eBay Rewards program (aka eBay Bucks). This new promotion, which started at 11am ET today and ends at 3am ET on Wednesday 10/14/15, requires, as usual, manual opt-in – you click the “Activate Now” in the offer email or message.
This offer gets you 4X eBay Bucks (= 8% of the purchase price) on individual items priced at $100 or more. You can use it as many times as you like during this promotion but the maximum rewards are $100 Rewards per single item, and $500 maximum Rewards total per customer.
The usual restrictions apply: “Qualifying purchase excludes all items in the following categories: Classifieds, Business & Industrial, Real Estate, eBay Gift Cards (within the Gift Cards & Coupons category), Bullion (within the Coins & Paper category), and eBay Motors”
eBay Rewards become available to you only if you have a balance of $5 or more, so if you are an occasional shopper or only buy low priced items, you may never see a penny out of them. Which is perhaps why they do these 4X promotions on more expensive items, since a single $100 item will get you $8 in rewards.
