Snapfish by HP has a really great deal running through September 30th.  You can create 5 personalized greeting cards and use code TRY5CARDS at checkout and pay only $2.49 in shipping and any state tax!  Wow, what a great deal.  Note that the cards you create must be ones regularly priced at $2.99 or less.  Look for the banner I have above at the bottom of the screen to get started.
