I think what will be more interesting is to see if peoples lists remain the same a year from now, after gas has been over $3 for an entire year. I know for us, we are starting to waiver on some of those "must haves". I no longer go to starbucks (shocking I know) Ive traded down to a cup at MCdonalds once a week only, much cheaper and pretty good stuff. Used to be a Kraft snob, but not when I can only get it at $1.18 a box vs .45 cents for Spartan brand! When Walmart has the Kraft on sale I stock up and since it takes two boxes to feed my family, I do a box of each, and no one is the wiser. I used to be a laudry detergent snob as well, and only use Tide or Era....I hate to think how much I wasted on those brands, when I now use Gain, and love it better then those other brands! Used Pampers for the first child, and like the commercial, figured out it was just like the Jif...trying to be the "choosy" mom, so I found a knock off of each that worked for my other children. Diapers can be tricky if your child gets rashes, I could never use Luvs, had to go with Walmart brand, but they worked great and saved me a ton.
I figure the part we do not go cheap on involves me staying home. Im very close to being able to go back to work, and man would it help us out, but I refuse to not give my third child all that we did our first two....she will be in school in a blink of an eye, and Ill be back working....I will never get those years back...so for that reason I dont compromise in that area.
I bought all they had in my size.

I drink a 2liter bottle a day! 
I try to get it on sale but it is the one thing I'm addicted to. Sorry no substitutions.
