I’m guessing everyone reading this (all 5 of you), have already heard of Groupon. But just in case it’s slipped by some of you, I thought I’d mention it here. If you haven’t already signed up for the daily Groupon emails, you need to get on that! Basically, each day there is a new Groupon deal that you can receive by email. The trick is, the deal only goes through if enough people purchase that day’s offer, which almost always happens. If you’re still not convinced of Groupon’s general awesomeness, check out some of their recent offers.
