The cards arrived quickly and were well packed.  I am pleased at the price and the service.  One thing that would have made this even better is if they had provided some instructions on how to activate the cards.  At first, I went to the AT&T site and had an online chat session with one of their support folks who said that I had to take the card and the phone to an AT&T store to get them activated.  This plan would not work well for my particular situation so I dug further.  Fortunately, I was able to derive what I needed to do but going through the reviews which is go to [...] and under "Shop", select "Wireless" then select "Prepaid GoPhone Plans".  On the next screen, select "Activate Account" (actually the "Activate Now" button under "Activate Account").  On the next screen, start typing in your phone's information under "To Begin Activation, Enter Your SIM Card Number" and follow the rest of the process.
