I kick myself...I could have bought silver at $29/oz spot price, and didn't. Now, I don't know. It's going up so fast, I hate to buy in and get screwed if it comes down.
I use Kroger's e-coupons, and try to buy stuff on sale with the e-coupons. Then I try to buy in quantity when I can get something cheap. "Buy it cheap and stack it deep" is my motto. If it is a consumable, that's what I do, because I don't want to have to buy things later at full price. You have to be careful about rotating your stock, or you'll end up wasting money. Then that is false economy.
Consider paring down regular expenses, like auto insurance. If your vehicle is paid off, and is high mileage, you might consider dropping off the coverage beyond liability.
Consider down-grading. If your auto payments are too high, maybe sell your vehicle and get a cheaper one with lower payments that you can afford more comfortably. If your cell phone plan is too expensive, consider getting a cheaper plan. If your ISP bill is too expensive, consider a slower level.
Consider switching cell phone/internet ISP/cable/insurance/etc
companies. They are all competing, and let them bid for your business.
