Delayed instant gratification

Two weeks or so ago when I placed my last grocery order with Amazon, I checked to see if they had Jim Gaffigan's latest DVD in stock.  The main Amazon.com store did, but it was not available for delivery with groceries for a few days—many Amazon items are available in as little as four hours in the Seattle area through Amazon Now, as well as a full selection of groceries.  Had I just ordered it two weeks ago from the main Amazon.com with the slow super saver shipping I'd already have it by now.  But instead, I waited so I could get it with the ultra-fast Amazon Now delivery.  It became obvious very quickly how little sense this delayed instant gratification made.
