One of my and many peoples downfalls of spending money is impulse purchasing. It is so easy and fast to just buy something up, but many a time I have buyers remorse after my quick purchase. So, to stop this I have come up with a waiting period for purchasing. I am not talking about spending $5 on a cute little bag but on bigger things. Say I see an amazing pair of boots in the store and they are $75. I really want them right now, but will I feel that way in a few days? I wait and mull it over. If 2 days pass and I still can't live without them, I will get them. Sometimes all it takes is time and some thinking to realize that you don't need an item. Many times I don't even remember what I wanted.
I understand this does not really work well with auction sites and other sites like the egl sales comm. Even there you might find your time waited worked. There have been several items that I have seen and immediately wanted but I waited and 2 days later it is still up for grabs. And because I waited a few days I asked for a cheaper price and got it.
Try it. If you don't save a little money I would be very surprised.
