Funny story:
Back in college, I used to sell my used textbooks on Amazon. One of the books that sold was at my parents' house, not with me in my dorm. The customer ordered the faster shipping. I called my mom to ship it for me and she took that to mean "overnight." It took the cost of shipping from about $8 to $25. That was far more than my book even sold for. Thankfully, my mom felt horrible and gave me the difference from her own account. Being a broke college student and all. ;)
Funny now, not then. lol. But that just goes to prove that expedited can mean different things to different people. :)
