Similar to Wal Mart, Walgreens has 1 hour photo. To get your 20 free prints, sign up for an account at http://www.walgreens.com.

Click on Photo, and upload your first photo. Once you do that, you will automatically be credited 20 free prints (glossy only for pick up in store). No shipping charges if you choose to pick up in store amd no credit card info required.

One more thing, you can create more than one user. Then you get print 20 prints for each user, and just pick them up all at the same time.
