This is an accepted solution.
Nick here from Shopify.
I just want to make sure I completely understand what you're looking for as I'm not 100% clear. Are you looking for a dropshipping/ wholesale app which sells/ ships bakers yeast specifically? If that is what you're looking for, I took a look but wasn't able to find anything within the Shopify App store for this as it is quite a specific product.
I did, however, find some dry yeast wholesalers which could be worth your time looking into. You can see them below:
Hopefully, this helps and gives you some direction with the next steps to take here.
All the best, Nick
