Amazon is now offering a $79 unlimited 2-day shipping option and I have to say that's absolutely brilliant. It probably would take only 4-5 items delivered in one year to pay for itself, and make xmas shopping much cheaper.

Lots of businesses have programs to reward their heavy customers while still making a profit off their casual ones but I never would have thought Amazon could come up with a compelling package like this. Pretty cool that you can share it with four folks as well.
