I liked Gumroad's sales page. It's uniform across all sellers on the platform and it's short, sweet and works. On similar platforms I've tried in the past, it was totally different, requiring you to either have no sales page or create one on your own, which always fell flat for me. I also like that Gumroad has a "marketplace" which is their Discover page where all their products can potentiall live. Buyers can go to Discover and just start shopping, like Amazon. I decided just to give it a go on Gumroad and it's worked out so far.
