I have three po boxes, in two states. I can send mail to any of them, and keep some of my anonymity... but I can't pass up Breyers for $2.69 (last nite at Food Lion, MVP) v. $4.59 regularly and cokes for $2.99 v. $4.19!
They can try to push to me all they want. I use my two cards (one for albertson's and one for a Kroger's company called Smith's) gleefully, and throw all literature mailed to me away...
The religious groups I donate to (mostly CRS) don't seem to shop their lists around.
Although one of the clothes stores I mailorder from must trade lists...all of a sudden, I'm getting Victoria's Secrets catalogs.
I find paper spam less troubling and easier to deal with than electronic, though. The Circular File (a/k/a file 13, or even the trash can) is a wonderful tool...
If anyone is interested in the fact that I buy lots of Genisoy Soy Chips, well, more power to them.
