I'm going to sound like a "pusher", but DO IT, DO IT, DO IT! I've been doing it for well over a year now, and we are saving a fortune! It can be a little overwhelming and frustruting till you get the hang of it, but stick with the first 4 weeks, and you'll never regret it!
Until you get a "stockpile" going, you'll feel like you are still spending the same amount of money, but remember to step back and see what all you are getting for that money. I'm certain you will realize you are getting better products, and more of them by far.
My husband now laughs that we never have to make a quick run to the store for ANYTHING!There is always an extra (or a few extra) stashed somewhere.
I receive so many items for free or nearly free, that it enables us to donate quite a bit to local charities as well. That makes it worth my time all by itself.
