Robert your email answer is correct!....My Aunt in Western Pennsylvania has totes of this stuff, all labeled and filed, and it is one big chore to prepare and seperate and mail this stuff in, each manufacturer is different, some want just the UPC mailed in, others the front cover, some a box top, a few the whole package, she has a book of who gets what and how many per envelope, for a windower with a small Social Security income, this helps her out a lot, they send her checks for cash as well as coupons to buy more of their products, somewhat of a vicious cycle.....people do what they have to to survive....odd though her house and contents is vintage by luck, she saved and bought and made stuff last, from the Norge fridge with the metal icetrays, to the Frigidaire double oven stove, to the Maytag wringer, to the Philco TV , all of which still works, we go to visit and it's like going back in time, she got indoor hot water and a bathroom about 1992...but still has to bring in coal to bank the furnace in the winter...odd to us but a way of life for her and the neighbors, their just used to it...
what a great find though just the same....ideas for this stuff is endless...
