Good post from the Justia legal blog about Stamps.com relaunching their personalized US postage stamp program.
You can use your own photos to make custom official US postage photo stamps. Law Firms can use photo stamps as an inexpensive way to market their services (the stamp cost is about 1.6x – 2.3x the price of postage, with additional higher volume discounts (see photo stamps pricing)).
This would be a great idea for law firms or really anyone to promote their brand to clients or potential clients. Its also inexpensive and very unique.
