ALL THAT MONEY JUST FOR A TRACKING NUMBER
I find the difference in price interesting. See for the larger price you get it only slightly sooner and get a tracking number. For standard shipping you don't get a tracking number. Here's the deal, the system tracks the package and that "tracking number" exists no matter what level of shipping you pay for. The only difference is you have to pay them to get the number. It's like going into a romantic cafe and there is a candle on the table and the waiter says "for $7 I'll light the candle for you".
