I get the Service Memories monthly newsletter which is filled with new products as well as techniques, and other great tid bits of information to use for various projects. You can search for products by branch of service which includes all the armed forces, firefighters, law enforcement, etc.; and they have rubber stamps too. They have great products such as: die cuts; various embellishments; paper for the Revolutionary War up to Iraqi Freedom; etc.
Here is their website, you should take a look http://www.servicememories.
Also, I added their blog to my blog list.
