I have downloaded your trial version and I am testing it now to see if would work for me.  So far it looks great.  I do have one question though: How do I do a FREE trial?

 I recommend when you go to check out and you click on the “Next Step” button the code sees what the current value is on the item(s) in the cart.  If the value is 0.00 instead of going to the PaymentDetails.aspx, it would either add the new role, or it would take them to the “you must be a member…join page”.

Please let me know if this is possible.

Thanks,

Rob

After a few more minutes of thinking I was thinking another (perhaps more attractive way) is to allow a free trial that automatically renews in a paying subscription when it expires.  This would allow you to get the billing info unless the person cancels a subscription.  However, the first method above seems easiest to code as you can access the ShopControlUtility.Instance().GetCurrentCart(price?) and if “0” then redirect to a different page….

To make this type of subscription work you would need a "temporary" subscription role that would change into a paying subscription role after the first expires...

This would take more coding on your part, but might be a great addition to your product.

Hi Rob,

  Thanks for the question, to allow for this replace the current cartsummary.aspx with the following:
