Vistaprint is offering 10 free personalized notecards. I love to create ours with a generic design on them so that we can easily just put anything on the note (thank you, congratulations, etc) on them and drop them into the mail. Shipping is around $5 on this offer.
If you happen to have a party coming up soon, these would be a great way to make some personalized party invitations — for only the cost of shipping. We ‘ve used their cards in the past for lots of various events and have never been disappointed.
