Hi all! One of my favorite mobile apps that I use to shop for the items I need is Offerup. I like that it's so easy to use and that there are usually a lot of ads in my area. I've even sold a few items myself on the app and it's always been a positive experience. And only once I had a problem with the seller, but I did not look for an offerup phone number I wrote to the support service directly in this application, and they offered me ways to resolve the conflict, so I was satisfied.
