Blippy and Swipely both launched fairly recently with the hopes of making spending a social experience. Both services are very similar in that they both allow you to connect your bank and credit card info, as well as other accounts like iTunes and Amazon. After you've set everything up, as you start spending, you have the option to share these purchases with everyone. And now you can extend that sharing with the Blippy API.
Google may not have landed Groupon in its quest for traction in daily deals. Instead, it acquired The Dealmap, an aggregator of local coupons. With the purchase by the search giant, we now list 89 Google APIs in our directory, with The Dealmap API now part of the Google arsenal.
