This app is almost awesome. It's a great idea, super easy to use, customize, install, etc. I wish all apps were this easy. But then I came back here and noticed there was a review (scroll to the bottom) mentioning that it covers half the page when using mobile. I tested it out, and for the first second I thought it would be fine, the tab on the side didn't really cover too much, it was thin enough, but then the coupon popped out without me even touching anything. The coupon not only covered the entire screen, but it wouldn't close. I uninstalled this immediately after. I'm so glad I read that as I probably wouldn't have noticed for a while, leaving my site completely unusable on moblie. So, yeah, almost awesome. If there was a way for it to not show up on the mobile version of my side, it would be totally awesome.
