Don, I agree; the Prime membership works very well for us too. We do a lot of video streaming, and I love the two-day shipping on most items comes in handy with computer repair parts I order, and REALLY came in handy with my daughter's college class books (the money we saved was astounding).
Better yet, if I need a computer part pronto to get a client up and running, it's usually just a few dollars to upgrade to overnight shipping. That alone pays for the membership with just a few orders.
