Create a purchase dependency on a product that requries anoth products previous purchase.

[kstroker]

I need the ability to block an upgrade product purchase until the base product has been purchased. For example, we have a bronze, silver, and gold version of a product, and users may purchase upgrades between the packages. I need to be able to block the purchase of upgrade products unless another product(s) have been purchased already in a previous transaction.

Hi @kstroker 

Yes, this can be achieved via custom coding in the theme.

We just need to iterate the whole order list of user and check if he has lower level or order in transactions, if order not found.

We can hide the buy buttons from page and display msg of not available for upgrade.

Hope this will help...
