I buy them and place perfectly located for patrons of the laundry shops or the free health clinic.
I suppose that is the risk you take in Placing™ your Literature™ in public places rather than with private Householders™. If you don't like going Door-to-Door™ and speaking to actual people, you have to assume the risks. Public places often have policies against solicitation, even though your definition does not match theirs. They don't care what happens to your Literature™ after you sneak it in and slide it under a couple of other periodicals. I've often seen colleagues find them in the pile and toss them right in the trash, just like the cashier at the dollar store. I've seen patients at my workplace find them and deface them - far worse than anyone here does with a contrary point of view.
If you don't like what happens to the Magazines™ after you Place™ them, you have a couple of options as I see it: 1) don't give them away - do as the WTS suggests and ask for the Voluntary Donation™ toward the World Wide Education Work™; 2) stop paying for them yourself; 3) don't leave them somewhere that they risk being "defaced"; 4) just stop - use the Bible only for your Ministry - the Word of God is a two-edged sword, is it not? Save the WTS some money and just use the Scriptures, like Jesus did.
BTW: When JWs procure Literature™ for use in their Ministry™, they don't call it "buying". It's a Voluntary Donation™. It is not considered an exchange of currency for goods and services.
