I haven't done much with my rock business this summer.  I was flea-bitten (or something) and I didn't print up new business cards as planned, or place ads in the local shopper.  I did, however, sell a couple of articles on birthstones and I made a handful of infomercials in the virtual world called SecondLife.  Those were fun to do!  I also acquired inventory through purchase and trade.  I chose stones with an eye to jewelry making next winter.  And the trade was great!  Also, I now market Thunder Bay amethyst.
