ooooo, that is an interesting one. Never tried that.

I have had to buy multiple books but of the same one but never different.

I have just tried to connect back in to my mac but my aperture drive seems to be switched off.

Have you tried holding down command and selecting the books then go to buy book?

I am working in the dark here without my mac, just the way I thought it might have been done.

Only thing you can do is specify how many copies. Each order must be a single design and sent to the same address. For example, if you want the same book sent to yourself and a family member, you must place 2 separate orders. Different book designs must also be separate orders.
