The popover that offers 10% off when your mouse leaves the page, it pops way too often, in a couple of minutes it poped 3 times for me... people do change tabs nowadays and if such a things appears more than once (maybe twice) it starts bothering the client, as opposed to drawing him in.
Also, you should make the bottom big orange bar dismissable, because it's annoying to have it there on all the pages and all the time.
