Confused on how ungating work with grocery items

Everywhere i go people say the same thing. Go to frontier coop and get ungated there. Issue is i dont see any of the products i want to sell in frontier coop.

An example would be dove chocolate. I cant find any on frontier coop. Does this mean i cant get ungated in dove chocolate or if i get ungated with another items like spices it ungates me in every grocery category???
