@Lachlan-Peter In my experience, the minimum quantity for Omega2S is a tray of 50 pieces. There also seems to be a sample pack of 5 at a higher price per piece. IMHO both very reasonable offers for starting a small product.
As I already bought 500+ Omega2S by now, I can‘t really tell how restrictive Onion is in granting access to their b2b ordering site for new customers. But I would guess they will respond to a professional inquiry sent to email@example.com ;-)
