Yes, art supplies are expensive. No, I don't sympathize with you. Buy the fucking paint or get out of the store, Jesus.
I still get a discount on all the art supplies I buy though, right?
Totally tempted to respond with "You get a discount on *me*," but I think Chris would hit me
Rowr! 
How about this: your next orgy is 50% off!
(tell me if I'm going too far)
What's the point if you've only got it 50% off?
