You can get as many items (as the store will allow you), and the register will automatically take off the amount per item in your transaction. ES qs can be used again, but ymmv so just make sure you get more than one copy in case they want to take the q. About the RRs, I'm not sure what your question is. I just want to say that as long as the 2 products are from 2 different deals, you'll get 2 RRs. You can't roll them into same deal, or you won't get your RRs back. You CAN use them for the same deal though, but no RRs for the next go.
