Shutterfly offers a greeting or stationery card
via coupon code "CARD4U". With 99 cents
for shipping, that's tied with last month's mention as the best deal we've seen on a single card at Shutterfly. (We saw ten free cards for new customers with $6 shipping last month.) Of note, you can get free shipping with orders of $30 or more via coupon code "SHIP30"; it stacks with the above offer.
