eBay is trying to get people to upgrade their app to the latest version, and they’re willing to pay out a small bonus. You can get $10 to spend on the new eBay app. Just use code MYAPP5COUPON to get $10 off your purchase through March 15, 2019 – only available when checking out in the new eBay app (version 5.0 or newer).
This is a targeted offer, most likely to those who have the older version of the app and you need to have received an email for it to work. But you can still test it out.
There’s also an eBay Bucks offer where you can earn 8% or 10% through app if you’re targeted.
