LPT: If you order pizza from a large chain (Papa Johns, Pizza Hut, Dominos, etc) and the pizza is delivered late, call and ask for a discount. Most places won't advertise this but they will give you one if you ask.

I actually didn't even know about this until I called to check on an order and the person who answered said they would give me a discount since it was late. The most I got was $13 off a $23 order and, at least for me, it really helps making waiting longer not so annoying because I'm saving money.
