Just think of the situation where you don't have to go to a store, select a card, wait in line to pay for it, go to the post office, pick up some stamps, etc., etc. Wouldn't it be much easier just to fill out a form and have Gmail handle the rest? Yes that's true. Google is now sending snail-mail a free holiday postcard on your behalf. All you need to do is fill out the form a Holiday Cards and leave the rest for Google to do it. Google has provided this feature only for the US citizens and to the limited number of people. So don't wait grab it ASAP. Wishing you all Happy Holidays!
