got my bitcoin lightning/on-chain web shop working. You can set prices in btc or fiat. You can sell both digital or physical goods, the checkout will ask only for mail address if you buy digital goods. You get to set price for different shipping fees in there according to your postal fees. You'll get a link to your digital goods if buying, where all digital goods from same email are... here's couple workin examples https://shop.tarina.org/ https://rockmanbrothers.com/ aaaand here's the source code https://dev.tarina.org/p/thiswebshoprules/ if you wanna get down to it.
