It actually surprises me that the brothers & sisters are so conscientous about contributing for the mags.
Even when I was a true believer, after the donation arrangement came in and we stopped charging for the mags on the doors, I kind of adopted a 'sale or return' attitude toward the literature.
I'd take, say, 5 WT & 5 Awakes, per issue for 20 per month, I'd 'place' about 12 on service, and 8 would go on the unplaced magazine pile. If I got a donation for the mags, which was rare since I never asked for money, I would of course put that contribution in the box. I think I viewed it that my contribution was my time.
