CityPockets is a service that aggregates all daily deals and coupons from various deal sites, such as LivingSocial, Yelp, DailyCandy, Groupon, and BuyWithMe. CityPockets also sends email reminders when a voucher is about to expire, and they also offer a marketplace where users can sell vouchers they can't use.
The CityPockets API is coming soon. No documentation or information is available yet, but those interested should email firstname.lastname@example.org for more information.
