If you run a small business, you inevitably spend a great deal of your time in the post office. Pitney Bowes, a manufacturer of corporate mailroom equipment, has a way to make mass-mailings easier as well as more noticeable. Its StampExpressions printing kit allows you to design custom stamps with (almost) any image you like on it, and then print out the image and stamp to personalize mass mailings, brochures, or whatever else your business mails out. The printer costs $159.99 and comes with a 5-lb scale and a label roll. There is no fee and no commitment to use StampExpressions, and it could be a great way to get customers to pay attention to your mail.

Even if you don't run a business, you can have fun with printing your own stamps--or, rather, letting Pitney Bowes print them for you. With StampsExpression Personal Postage, you upload whatever image you want to appear on your stamps, and they do the rest. It's a fun way to send out those Mother's Day cards!
