@davper Thanks for that info (your wife getting the 4x promotion without having earned eBucks before).
Here's a new theory- maybe it has to do with the age of the account, and whether or not you earned eBucks before? I've had my eBay account for well over a decade, just signed up for eBucks about 3 weeks ago, and have yet to receive a #X promotion. Maybe on an old account you have to earn and spend eBucks before getting the promotions? And on a new account signed up for eBucks, you start getting the promotions more quickly? Just another theory, it may just be random. I am considering opening another eBay account if I don't start getting the promotions in the next few weeks (ie after I can spend my eBucks)
