Come out, come out, wherever you are: Good luck finding all the hidden taxes you pay

You're a responsible consumer, use coupons, track sales, and in general try to be a savvy shopper. But do you know how much of your spending goes to taxes?

I don't, and I even tried to keep track. At the beginning of this month, I held onto every receipt and went so far as to create a spreadsheet. Different taxes would be logged in the appropriate columns.

But it was a futile experiment and I abandoned the exercise in just a few days. Why? Because sales tax is such a convoluted and complex system, that I defy anyone to figure out just how much of what they spend is a tax.
