What's Your Point?

No, really - what's your point?  For purchases, establish a personal price point that you will not exceed.  For example, if you are a regular soda buyer, make your price point $3 for a 12-pack case.  Anything under, consider yourself getting a deal, like when they go on sale for three for $8.  The price point system is also useful to know when things are overpriced.  The other day, a grocery store was advertising the aforementioned soda as a deal at two cases for $8.88 (or one for $4.44), well above the price point of $3.
