How Many People Have to Participate in a 'Not Buy' before a Place Will Lower Its Prices?

(A 'not buy'---my making up for my 'aphasia' (knowing there's a "right" word, forgetting what it is))

As far as I know, no one's really counting (except maybe the manager, especially if they own the branch). The rest of them just go in, do their job & get their money---not even CARING how well one-or-another product does except as it is-or-isn't the next order-up.

If you want the place to stop selling a certain item, quietly 'not buying' it yourself (while others buy it just as frequently as before) isn't going to have much effect. So you can either a) go ahead & 'not buy' and be self-assured that most people are smart & will 'not buy' with you, b) organize a community-wide 'not buy,' knowing that it'll make the manager stop selling that product as a matter of course, c) write a letter to the people in charge of which products get sold, explaning to them why you think the product is a bad idea or d) discuss it with the manager/owner if you know them personally.

Do you think organizing the people would work better? or bringing it up to the owner/manager personally? And Why?
