Aaah ok, thanks makes sense, as not everyone wants to apply promotions to new products (I just assumed it would as I applied it fairly broadly to a bunch of my store categories - probably asking too much to hope for that to be optional, i.e. apply to new listings or not, as some people will be running store-wide promotions intended to be for all items and it could be quite a pain to update the promos each time new listings are added). 

DG - you can stop and restart promotions you have set up at any time in your manage promotions dashboard. If you list new products and want to include them I think if you have selected all store inventory for the promotion you should be able to put the promotion on hold for a minute and restart it. Otherwise you can end the existing promotion and copy the offer which only takes a few minutes.

Sweet, thanks 🙂 (Clearly, I A) don't generally expect there to be simple solutions on eBay , and B) have a bit more exploring to do with the way the promos work.:D)
