Sure, but you still only shipped one box. Anyone can match $10 or less to ship that including USPS. However, how much do you think FedEx is going to charge to get those 200 individual items out of that one box and on to their 200 individual destinations? I bet a lot more than $10. Hell, I bet a lot more than the $100 for individual worth in postage. I'd be willing to bet something more like at least $1000.

Sorry, but you lost all credibility in your second sentence by calling QuickTime a "player" that was ported to Windows. The player is just the most readily visible part of the whole, but I bet that you and the rest of your AVI can do anything/Windows Media Player loving folk already knew that.
