"Subscriptions didn't make a lot of money but they clearly weren't a loss. Because when the charge was dropped, subscriptions were dropped pretty quick too." - slimboyfat
That has absolutely NOTHING to do with the discussion at hand. If you can't charge a fee for the Watchtower magazine on the doorstep delivered by a WATCHTOWER drone, you can't charge a fee for a subscription delivered by the Postal Service. So of course they dropped subscriptions! (The only thing you could charge for would be a shipping and handling fee) It's just plain business sense. Actually, I wish that you would stick with your original premise and stop 'going around the barn' to defend the indefensible.
As a side note, I tried to show you that individual subscriptions consumed huge amounts of materials and labor compared to shipping magazines to local congregations. The 'gross profit margin' on an individual subscription would be much smaller than on a magazine hand delivered by a publisher. If you were never a Bethelite in Brooklyn or at Watchtower Farms I'm sure that this is hard for you to fathom.
