Nostr stores should support cashu payments sent in secure DMs. Buyer can reclaim the payment if seller doesn't reply.

Seller doesn't need a payment processing or e-commerce server, mobile phone is enough. Maybe the cheapest and easiest way to run a small online store.

Some sort of order management UI for buyer and seller on the client side would be nice.

Just thinking aloud, only tried Shopstr so far but should check out others as well (Amethyst?)

Pic kind of related, could be my dropshipping lifestyle store.
