Try to request some samples, you get them at discounted price and is worth to have them to check the quality.

Shopstr is cool too, but I feel there's so much going on there that the products get lost and loose visibility really quickly.

We tested that too 😅

Plebeian market is another good one https://plebeian.market/p/d2b323fffd132e0fa76fbad5313b1547e47fe5b0233c2c8ff5ff4c0fe6009b17/stall/614bb48db263665a414cb9d0e3053ab6ab97316edb6685ed6e51c923160b97d8

Just keep an eye on shipping costs when using the nostr shops!
