In the old days prior to the 1990 "donation" arrangement in the United States, regular publishers sold WTBTS literature at a 25% mark-up (20% discount over retail) over the price they paid at the Kingdom Hall literature desk. While the extra money was supposed to cover expenses, I don't recall anyone actually achieving this goal. Most people seemed to always have magazines left over that were eventually given away for free.
Pioneers of various ranks got a different pricing schedule. My memory is a little hazy on the exact numbers, but I seem to remember that there was a sliding scale with those who worked more hours getting lower prices and so higher allowed mark-ups. Full pioneers got the best deal with somewhere around a 300% mark-up (75% discount over retail); this was the way that the WTBTS "supported" the work. Yet even with this type of margin, I'm sure that the WTBTS was still making a nice profit.
Now that the "donation" arrangement is in place in those countries where the WTBTS would otherwise have to pay taxes, do pioneers today have any kind of support from the WTBTS? Do pioneers have a different and better "suggested" price list than other publishers?
