A neighbor is riding out the shutdown in Aruba, poor guy, and sent a gorgeous postcard of his latest fishing catch using the app Snapshot Postcard. This reminds me that I'm way behind the curve on printing and postcard services.
What's your favorite postcard app/service and why?
I'm interested in something that I don't have to pay per card, more like buy a dozen/pack or 25 credits and use them up as needed, and can also store them as an archive or album for re-use or later reference. What other features are you enjoying in your favorite?
I think Snapshot Postcard works on the fly once you've set up an account -- literally take a picture with your phone, type a message and a recipient, and the service does the rest, including postage.
I realize after a quick search that there are lots of competitors around, so that's why I want your guidance, RS folks.
