There is a great current offer from Fuji Film's online photo site, SeeHere, for 24 photocards @ $2.49 shipped! This deal comes around a few times a year it seems, as I used it last year to get very inexpensive baby announcements! You could use these for a variety of occasions as there are many templates available.
When you log in or create a new account, add (24) 4x8 photo cards to your cart and use code "25cards" at checkout to get the cards for free and pay only $2.49 for shipping!
Thanks, Money Saving Mom!
