Ok, so we set up a page with each version of OOTP (and FHM) listed, so you can add each of them to the cart and order them all at the same time.

Let me know if you have any trouble using it. And I know I'd mentioned getting you OOTP11 for free. So if you do end up ordering the rest, just order 11 along with them and send me a message with the order number and I'll issue a refund to get you $19.99 off the order.
