I asked myself the same thing! There are many images I want but I know I only want them for a couple cards. So...I joined WISH RAK here on SCS. I can get images I like but only need a few of for a couple cards. My husband likes that I am using my own stamps so much more...even if it is to fill other people's wishes. Some of my old sets have never seen so much ink and I get images I never would have bought just to use once!
Just an idea to help the addiction. It's working for me so far.
