Miles for Postage Stamps
If you don't already know, Safeway offers miles for purchaes. In DFW, a person can sign up for AA miles @ Tom Thumb. In Houston, I get CO miles @ Randall's. When my purchases over multiple purchases total $250, I get 125 miles. This is on top of miles on earn on my credit card and Upromise. Advance enrollment is required.
What you may not know is that purchases of postage stamps count towards earning miles. Something to keep in mind when getting stamps for holiday cards soon.
