In case you haven't noticed, there are more than a few group purchasing sites that have launched recently. Many of these sites have short windows for when you're actually able to purchase a particular deal. It was only a matter of time before a site popped up that offered users the chance buy deals when they're no longer available on their original sites. This site is called Lifesta. Think of them as the StubHub of great deals.
Not only can you search their database of deals that people are selling, but you can also sell deals yourselves. Perhaps you're looking to make a quick buck. Or maybe you just want unload a few Groupons off your hands. Whatever the case may be, Lifesta guarantees all purchases and you can download all vouchers directly from them immediately after they're purchased. Current deals include a $22 private kickboxing class and a personal wine tasting class for $12.50.
