My wife and I plan our meals out in advance, then go to the grocery store and buy only what we need. I eat the leftovers for lunch the next day, she takes a microwave Healthy Choice dinner.
I stopped buying bottles of wine in the 20-30 dollar range and started getting the box wine.
I have a voracious appetite for books, but I buy the majority of them from a used book store here in town. (I still treat myself to a first edition every once in a while)
I no longer purchase DVD's, and those that I did have I uploaded to my computer and got rid of the hardcopy to the same Used book store. I cut my collection from almost 400 to about 75.
This helps to feed my new addiction and my wife's Coach purse habit.
