I'm just getting started on setting up my TES shop and I was planning on selling a quiz that could be used in languages at the end of the year. I want to be able to make an updated version next year, but sell it separately. On the other hand, it would be nice to give some kind of discount to anybody who buys it this year. So I was wondering if I would be allowed to give it for free to anyone who reviews this year's quiz. Would I be allowed to do this? Thanks!
