I just got my Shutterfly order in the mail from when greeting cards were priced at .99 each. The price is a bit higher now but to me it still seems like a great deal compared to what you pay for a normal greeting card.
Shutterfly has cards on sale for 50% off- they are starting at .75 and most of the ones I saw were $1.50 each. You can customize them any way you like and shipping is .99 per card. I tested it with a card on sale for $1.50 and my total including tax and shipping was $2.64. (Just click on the design you like and you will see the price per card on the right side. Obviously the more of the same design that you choose, the lower the price.)
I made a quick trio of birthday cards for 3 grandparent birthdays we have coming up and I am extremely happy with the quality of the cards.
If you have any events coming up you might have a look at Shutterfly- just click on cards and there is no promo code needed. You will see the sale price on each design you select in red type.
You will get a nice card with a matching envelope and you can choose to have it sent to you or directly to your recipient for no extra cost!

I just opened my cards from shutterfly tonight, and I am extremely happy! The quality is great and I paid less than I if I would have walked into walmart and picked some out!! I also think that the $2.64 is still a good too for the quality and personal aspect of these cards!
I agree Morgan! I just bought a birthday card a few weeks ago at CVS and it was almost $4! I thought my cards looked fantastic.
