Our discussion about calling Good Sam's to get off their advertising mailing list got me to thinking about all the other junk mail I receive. Found this useful website to opt out of most of it.

The mail preference service listed in # 1 is free if you do it online. The info says they charge you $1.00, but not so. That one link gives you options to opt out of credit card & insurance offers, catalogs, magazines, & other advertising.
Scroll down to # 6 to get rid of "Valupak" coupons....one of things I always get and don't want.
Anyway, I knew this was possible....may have been discussed on here before....but I finally got around to do it.
