I have written already about different ways to sign your jewelry, and one way to do this is to use metal stamps. I recently heard from the Infinity Stamps company that it is having a sale during November 2012, so I'm passing along the information. Basically, November 1st through the 30th is what the company is calling "The 30 Day TagMate Sale." It is marking down a number of its "TagMate" systems during this time. You can all the details on the Infinity Stamps web site.
