Here's how. First things first:
If you are new to Groupon, you will need to sign up.
If you are new to Living Social, you will need to sign up.
Now, when you are looking at the Swagbucks homepage toolbar (at the top), go to Earn>Daily Deals. Scroll down and click the tab for Local Deals. Click on any deal you want to buy and follow the steps to complete your purchase.
I am a BIG fan of Groupon and Living Social and Swagbucks. I was thrilled when I learned that I could work both programs for more savings!
