Let's get this thread back on topic: Here's something I did in the last year:
My credit card has a feature, where they will reimburse me for the difference if I buy something, and then later find it for sale somewhere else for a lower price. This past year, I bought some minor thing, at a local store (for way more than it should cost) as a convenience because I wanted it immediately. The very next day, I filed a "claim" with my credit card, due to finding it for sale at an online retailer for a small fraction of the cost (like 1/5th of the cost). They reimbursed me. I try not to abuse this too much, or else they might get rid of this perk for that card.
This one reminded me of another credit card method, not sure if it's been mentioned already. Many credit cards will forgive a purchase if it is small enough and it is the only thing that posts to your statement that month.
