Ask HN: Alternatives to gumroad for payment and digital download

I make a digital product and want to sell it and so have been looking around for services that allow me to do it.

I haven't messed around with payments before but I've heard a bunch of good things about stripe so I checked it out and the payment side looks great but I'm still a bit fuzzy and the best way to fulfill the digital product.

Gumroad seems to be an option, and I like that I can just embed it on my existing site (rather than use squarespace, for example) but I feel like I'm missing something since I can't find any others,

Any tips on where I can look?
