There is a book that both my friend and I would like. I ordered one copy using a credit for it. Now I would like to order another copy and have it sent to her address and would use a credit for that one as well. When I tried to do this, I got a message about becoming a Gold Member. Are we not able to order the same titles we've ordered in the past? 

You can order the second copy once the first copy has been marked mailed. If you are a gold member, you can order multiples without waiting.

I see. Thank you!
