Gumroad makes it much easier to sell digital products online, provides sellers with a lot of features. The previous review states that "Gumroad is a scam" and I disagree, each product can be reviewed by the customer and I think you just need to do some research before making the purchase. If something goes wrong with a purchase you can simply open a dispute. It's the internet, there are going to be scams, but they can be avoided pretty easily.
