You can do a follow like and share to win a giftcard for example. Expand your following and reach more ppl on Nostr. Or just throw in a general discount for limited time. I know you don’t keep customer data but you really should build an (opt-in) mailing list to send out promotions etc. My wife has a webshop and that works really well if you use it to communicate on with your brands’ fans Or you can always buy Google, FG, IG ads if that’s your thing (but I think it’s not) Just some ideas ✌🏻
