I was the accounts servant for several years, including the year when the donation arrangement was implemented. Our congregation literature order was typically around 800 mags plus books, so we would remit at least $500 every month for literature. When the donation arrangement came in, our WorldWide Work donations were never over $100 - usually around $75. Talking to some other literature servants from other congs yeilded about the same numbers.
This is why they are crying for money.
