Lynn and Lisa,
The cool thing about SU's In-Colors is you can purchase the markers for fairly cheap. I use them to ink my stamps when I want to use those colors. If I find a color that I'm really using then I buy the ink pad with re-inker but I really wish they would offer the spots for those colors as well. As far as the color changes goes - the big one was just done this summer. They will probably not do another one for several years. The In-Colors will work like this - 2010 they gave us 5 new colors...2011 they gave us 5 more colors...in 2012 the 2010 ones will go away and they will add 5 new colors...in 2013 the 2011 ones will go away and they will add 5 new colors...you see how it goes.
