Vistaprint is offering 140 customizable labels for FREE. You just pay S&H which starts at $3.50. There are over 7,000 designs to choose from categorized by themes, colors, images, etc. These are also great as gift tags, envelope seals, book tags, holiday labels and so much more! I got these the last time they had this deal because we were getting ready to move and I love them.
This offer is good for TWO DAYS ONLY, April 3rd and 4th. If you are unfamiliar with Vistaprint, it is a great company and with my experience, shipping is always a lot faster than the estimated timeframe.
