We all love a good deal and recently there have been a proliferation of local deal sites (Groupon.com, Dealfind.com, Socialbuy.com, etc...). These sites offer great deals at local merchants, the deals are usually anywhere from 50-90% off regular retail price. Local merchants offer great deals to entice new customers and hope to build a long term customer base. Local deal sites also usually have some kind of reward program where you get credits towards future deals if you refer a friend to purchase a deal. The only problem are that the deals are usually short lived (1 to 3 days) so you have to make the purchase decision fairly quickly.
One way to stay abreast of all the daily deal sites is through a site called One Spout http://onespout.com/. Here you sign up to receive one email that has over 50 daily deal sites compiled into one email. This can save you from searching through loads of junk mail each day. If you're not interested in recieving a whole bunch of deals, one of the most popular local deal sites has been Groupon http://www.groupon.com/.
I recently got a great deal from Groupon. I purchased a full month of unlimited yoga classes at Pranalife Yoga for $35. Regular retail price is $90, that's a whopping 61% discount! I also purchased one for a friend and because that's considered a referral I get $10 credit towards my next Groupon purchase.
Here's a short video about how it works. Never pay more than you have to again!
