Instant download

I have a question about instant downloads I am trying to decide if I should do them. Is it profitable and worth doing? What are the pro and cons? Any advice is greatly appreciated. Thank you.

You don’t have to do anything. If the card is an item that has instant download as a purchase option for the customer, it shows that option automatically. You can disable it if you don’t want the customer to buy it that way. Sometimes a customer might want it as a download, or not at all. 

Have you sold any how do you know if someone buys it or if it is a regular sale just not sure how that all works. Thank you.
