I originally thought I might get a nontrivial amount of money coming from my associates account at Amazon. That hasn't happened yet. I tend to get $40 every 3 months. Recently it's been even less.
So I'll just say that I get a little revenue from this program and I spend it on good projects. This summer I decided to throw out about $3 thousand worth of receipts for section leader food, end-of-semester parties, grading parties, etc. I didn't want to sort out the receipts and I knew the staff didn't want to process them, so I just absorbed the expense. And last spring I had prizes in my cs335 class. So I spend far more money than I receive to support my teaching. The fact that I get some income from this program makes it a little easier for me to live with not getting reimbursed for special events.
So if you want to send a few bucks Stuart's way, make your Amazon purchases through the following link:
