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 really love the ability to automate my social media posts. I really feel it has helped increase my views and sales. it makes social media effortless. The Treasury tool is also great, and allows you to create treasuries with other sellers that are reciprocal. I have really liked Seller Tools!
