Dave told me you can get 3.5x5" prints from Wal-Mart.com for 22-cents each. He just uploads his digital pictures there and orders the prints he wants. Here's their photo center online: http://www.walmart.com/catalog/catalog.gsp?path=0:5426&dept=... If you order pictures there and pick them up yourself at your local Wal-Mart store, there is no shipping cost, either.
If those of us who have digital pictures could upload them to Wal-Mart's site, we could just order copies of the ones we want for ourselves. What do you think?
