Limiting a product purchase, based on previous purchases

[jedibudo]

I am selling online classes. I would like to sell them in a progression. Is there a way to prevent the purchase of a class based on the lack of a previous purchase? For example, a student wouldn't be able to purchase Lesson #2 with out first purchasing Lesson #1.

Unfortunately no, there is no way in EasyCart to base a purchase on a previous purchase.... You could build an option set with a yes/no question, just simply directing the user to make sure they have already purchased the previous class, but it is just a question, not a direct link to a previous purchase or check on that.
