Tax rates here and there, and "the system"

What fun! In my part of California, it is 8.25% (its a county thing!). If I have a really big ticket item, I just have it sent to my sister's place in Oregon where the rate is a very low 0.0%. California has various rates depending upon the locality. Oh, and there are other catches. A few hours ago, I bought a nice HOT roast beef sandwich. Tax charges. If I had asked it to be cold (as well as take-out/to go), no tax. Go figure. The rule is that if it is "hot edible" its taxable. If it is "cold, edible, take-out" there is no tax. All of this is to make sure that restaurants (especially fast food joints) charge tax, even on take-out orders. If they charged for "cold, edible, take-out" then they would also need to charge tax for groceries which isn't too attractive.

Fortunately, Amazon doesn't sell food that I know of.
