First, there is a sale on Zazzle.com of 50% OFF for ALL 
holiday cards through this Wednesday (10/30/13). Check it out.
My Zazzle Site.

Second, I have sold over 30 postcards and greeting cards--some
of various stamp macros. Too numerous to give them all, but here
is one using my Uruguay Bird Stamp. 

Third, just sold a pack of 25 postcards of my Fiddle Strings Macro!

Fourth and last, just sold a greeting card on FineArtAmerica.com
of my Yin Yang Abstract!
