Thank you for the reply.

As the required purchase item didn't have to be from their store, and as previously when I've tried downloading free products from vendors I didn't have this issue it was a surprize to me.

The store's free stuff is well known to me ;-) I also have put shares available to people but not through R as so many of the older links are dead that my concern is one cannot remove them when wishing to either update or simply withdraw them.
