I'm pretty sure everyone's heard of Living Social - the website/app where you can get daily deep discounts. Well, now they've launched something called Instant Deals where you have a limited amount of time to get a deal. This morning's, for instance is, spend $3 get $6 at Cacao, but you have to use at lunch during a specific time window. If you're flexible though, it's a great way to save some money.
