Reminds me of a friend's DW who LOVES going out and "finding a great deal". She will crow on and on about "I saved X amount of $ when I bought this!" and I recently made a comment to her saying that you aren't SAVING when you are SPENDING. Oddly enough, she doesn't seem to like hanging around me too much anymore.
That sounds like my ex. She came back from shopping and proudly exclaimed that she had "saved" 30% to 50% on everything. I then asked "How much would you have saved if you'd stayed home". That didn't go over well.
I guess that's why we're not married anymore....
