I am looking at https://gumroad.com/features/pricing -> how is this different from setting up my own shopify website for eBook. I am doing this today with $0.30 + 3% per transaction. Does Gumroad have any exclusivity? I am sure they have a bigger reach than my website and love their business model -- this is very fair. btw, my website is www.thenextinnings.com and the eBook is on sale at $2.99 I have enough details about the book and you can buy if you like the storyline. thanks for the tips!
