We have a grocery store that offers online shopping and home delivery, and you can take all week to add to/edit your order. I've found that it eliminates impulse purchases, but you really have to be careful with your purchases. It's very easy to spend more for an item than you want to just because they're coming anyway.
How are you at sticking to a budget? Mrs. WI simply cannot. She claims to know all of the expenses off the top of her head, but I'm sure she would be shocked to see what some of the "minor" things add up to.
One thing we've tossed about is cutting cable back down to basic. We spent $75 a month to watch 20 out of 200 channels! That's a lot to pay for a glimpse or two of boobs.
There's obvious benefits in adjusting the thermostats to cheaper settings. Especially with the cost of utilities skyrocketting. Though it's impossible not to drive, we do try not to take extra trips out. And we'll try to have our route's make sense. Nothing like passing the same landmark three or four times in one trip...makes you think of European Vacation. (hey look kids...it's Big Ben...and there's Parliment)
One thing we must do is eat home-prepared food more often. It's more healthy, we will have better portion control, and it's a damn sight cheaper. It's funny how I manage to make lunches for the kids every day but end up buying lunch for me.
While we're cooking, I've given more thought to "multi-meal" ideas as well. If I'm running the oven to cook two chicken breasts...why not cook all of them? Then I can use the extra to create another meal that will only need to be warmed up! Anything that helps cut down on how long I run that stove!
