Hi, I have a couple of questions.

  1. Are themes refundable?
  2. Can we move themes from one WordPress host to another?
  1. only if they are broken. More info here

  2. each license is for one website. If you move this website to another host then it should be fine, but if you want to use it on a different website then you need to either buy a second license or else deregister and delete the first copy
