Walgreens has an offer that is a good way to save a few dollars on items that you need. The offer is $10 off a $50 purchase at www.walgreens.com. The only exceptions to the savings that I noticed is contact lenses, electronics, photo orders, and gift cards. This offer ends November 5th 2011.
Walgreens also has free shipping for online orders over $25 for up to 10 pounds. There is an additional .49 for each additional pound.
