I'm in, but seriously...
If you want to be more efficient with your spending, write out everything you spent money on (bills, food, movies, eeeeverything) for the next three months (July - September). Then start trimming the fat. Can you go without new games until New Year (Oct - Dec)? Can you invite your friends to eat-in instead of take-out (or pot-luck at home)? Will store-brand soap work OK instead of name-brand?
Then like punished_snake suggested, improve your lifestyle. Solar panels to curb your bills, efficient gas to clean your car, putting bottles of pebbles in your toilet water tank to save per flush, buying more fruits/veggies and nuts/eggs to keep you filled so you don't buy expensive snacks or meats, use fans and ice-packs instead of the A/C...
And investment advice? Don't use a savings of checking account; the interest rates are lower than the inflation rates (in the USA). Stuff your money into your company 401k, your personal IRA, even CDs if you just want to avoid the temptation of spending money. These things require the least amount of fiddling from you.
Put your next tax rebate into US treasury bonds, or in high-yield blue-chip stocks. Stuff like Microsoft, McDonalds, etc. will be steady with inflation -- a single big-bulk investment via E-Trade or Scottrade (which have a fixed-rate charge instead of a variable one, making bulk investments more economical) will adjust with inflation. You might not make a lot of money over the next year, but it will be worth more than if you had put it in a checking account or even stuffed under your pillow.
Oh yes.
One caveat to buying in bulk -- in the case of food, they go bad. The economical packages are too big for you to finish off. In the case of supplies, the no-name brands might be inefficient (e.g. soap that requires more scrubbing to clean as well as Ivory). And finally, for big things like fridges and air conditioners and heaters, look at the Energy Efficiency ratings so they don't drain you when they're continuously on.
