1 free per month?

I’m considering purchasing eStore, but My client wants users to be able to access one free eproduct per month. Is there a way to do this with eStore?

Or at least to allow one free eproduct, and then charge from then on if they try to access any other eproducts?

If not, is this something you would consider adding for a fee?

I could use the squeeze page form, but I need to capture more information about each user. Is there a way to add custom fields to the squeeze form?
