I had a problem as well, it happened many months ago. I rented a store and received no group invite. Almost 2 weeks later the owner answered my IMs and offered what he told here (quoted above). I decided on the refund, since I had already rented elsewhere.
What is worth to create nowadays? Talking about prims, because I don't know how to create mesh (I tried before, but didn't succed).
I think nobody buys itens made in prims anymore, am I right?
Sorry for my English.
