I generally make it a rule to wait until a gadget appears on Amazon before buying it because the prices are usually lower, there’s no tax, and most items are eligible for free shipping. The last point is especially important for me because a lot of other retailers don’t seem to know that Hawaii (where I live) is actually part of the United States. Expensive overnight shipping (which actually takes two days) isn’t the only way a package can make it across the Pacific Ocean, other retailers; the U.S. Post Office delivers to our little grass shacks too.
