Problems - AMember & 1ShoppingCart

I have not rolled this out, as I cannot find a solution that works yet.

I am trying to do a forced continuity program where you have to buy a product and then you are enrolled in a members PHPBB3 forum. One month free and then $3/month.

It's perfect because they can buy 100 books and leave the membership there as one. Or they can cancel the membership, but they cannot cancel the book.

So I bought Amember, and they now say it cannot work that way. If I set up a product with only a single copy of the product (some may buy multiple copies for groups), and then set up the product separately so people can buy as many as they want, that seems to defeat the purpose.

Does anyone know how to make this work or if another product will work better?

Is there a program that will generate a username and password that I can send with an autoresponder after the sale?

I have also looked at Interlogy profile manager premium.

I've been trying to figreu this out for weeks now. I see people with forced continuity all the time and don't see the problem I am having.

Thanks for your help.
