I think that sounds like a good rule-when I ship from home (almost always!) I always get the DC-it is free, so why not? I have forgotten to do it a time or two when I had to go to the post office, however. I learned my lesson, though, with the gift card I sold. I would do it on anything-you can put a gift card in a priority mail envelope and put DC on it. Yes, it costs more than .44, but a $10 gift card is already below the value of some people's swaps, and many of us pay another $8-10 to ship too. You can always do paypal if you don't want to pay the extra to send a gift card.
