Can you get ZYNs on Instacart?

Excuse me, but I was wondering if you could possibly clarify something for me. I've been hearing a lot about ZYNs lately, and I'm curious if they're available for purchase on Instacart, the grocery delivery service. I've searched the app and couldn't find them, so I wanted to know if I'm missing something or if ZYNs simply aren't offered on the platform. Could you possibly shed some light on this for me? I'd really appreciate it.
