I would add to that list of small indulgences that we can't live without:
A tiny tube of wrinkle-erasing under-eye cream that costs $27. Well, it's cheaper than plastic surgery!
High-end shampoo and conditioner. I am working towards generic versions, which are probably just as good, but am not there yet.
L'Occitane hand cream.
Going to the dermatologist for zits.
*** On the other hand, I took my kids out to dinner at a diner last night, and the bill for the three of us came to $46.40 including tax, tip, and a side of fries.
