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 the ease of promoting items in my shop through social media. I love that I can set automated promos as well as manual, because I can promote new listings easily manually and promote my existing listings with the automated version.
I especially like the promotion tools which has easy schedule set up with all options I need. Saving a LOT of time on a daily basis! Keyword and trend tools give information to think about and to improve the tags and titles, really helpful. And since this is dynamic, you can stay tuned to the changes in the area of your interest with no waste of time for search it in other way.
