I've never experienced scheduled posts for social media -- love it! Easily posting my listing reviews to social media is excellent! It's one of those things that's so awkward to do manually. Surprised with attentive and personal attention through the built in conversations and really appreciate that.
I love the simplicity of scheduling posts. I had been trying to keep up with that myself, and some days (like the last four) were so crazy I wouldn't post at all. Scheduling sales events is super simple as well, and you make the graphic for me, which was fantastic! Having the red text draws the eye, and really stands out. I have yet to try Favathons, but I'm working on Clickathons a little bit several times a day. I have already seen results in traffic to my shop!
I love all of the promotional and shop data tools Seller Tools provides. These proved to be very useful features. And I was very pleased with the excellent technical support!
