Here are a few lessons I've learned selling physical goods for sats/Bitcoin.

1- Have multiple Lightning wallets up just in case something goes wrong with any of them. @`ZEUS`has a POS system that is useful if you're selling the same-priced items. Generally having this setup maximizes the ideal checkout experience (one QR code, quickly drawn out, quick scan). Make sure to do liquidity management if it's your own node before major events.

2- It's a powerful thing to offer items for sale with the default option for most people (cards) removed.

3- From what I can see people love paying for goods in sats, there's a rush to it, and it's a way to further orange-pill. Yes, there are abstract debates on store-of-value and medium-of-exchange, but try to beat the feeling of zapping someone magic Internet money for something that ends up in your hands that minute.

4- Bitcoiners love physical, tangible goods like books.
