thats right. take a picture or an image and incorporate it into your own personal stamp. a pic of the kids, the dog, or whatever you want can be printed legitimately by the USPS.
you get 20 stamps per sheet starting at $17.99 (.41 cent stamps) and pricing discounted if you buy in bulk. you can upload whatever image you want and edit text and fonts with its huge array of customizing options.
go to Zazzle and they also have a bunch of other stuff you can personalize too – sorta like cafe press but cooler….
