How to get a Milk Pail?

I'm curious, could you please explain in detail the steps one needs to follow in order to acquire a milk pail? Is it something that can be purchased at a store, or is there a specific method or process involved? I'm particularly interested in knowing if there are any considerations or factors I should be aware of before making a purchase. Additionally, are there any alternatives or substitutes for a milk pail that could serve the same purpose? I would appreciate your insights and guidance on this matter.
