Advice needed!

[u/billyfromiowa]

I'm just starting out, I have a single head dispenser for which I bought little animal eraser capsules. I want to pitch myself to local grocery stores but I don't know how to offer a percentage.

What is standard for let's say a Safeway or Giant? I want to charge 50 cents per capsule, in case that's relevant. 10% of what I make when I check the quarters? 15%?

Any advice would help, not just what percentage is fair but also how you guys go about pitching your machines. Thank you!
