Thanks Madisgram and Splitimage,

How do I support this person once I've said what my concern is? Do I refuse to go shopping/spending with this person? Do I come up with other "free" things to do?

This bad spending over budget is a huge problem. Person doesn't seem to care even though there is knowledge that there are responsibilies that need to come first.

Is it really a "thrill" feeling? I don't really understand that because I don't get a thrill or high out of spending when I know the electric bill is due and I have only enough to pay the bill. Maybe that is because I tend toward depression and don't need a lot of "things" to feel good.

No, this life long friend doesn't have/hasn't had any addiction prior to this spending thing.
