Go to your email and Activate your account. Make your first purchase at a minimal cost to support my shared referral methodology.
After making your first purchase, click on Refer Friends, Get $10.
Here is the trick to having an endless source of Groupon bucks, so long as you have an endless list of friends/emails.
Send the link to your friends and to your "secondary" emails. Sign up with your "secondary" email by clicking through the referral link you sent. Register with a new name. Once you make your first purchase with that email, even if less than $10, your original referring account will get credited 10 GROUPON BUCKS.
You can Refer Friends from your primary or secondary account as you please and get credited 10 GROUPON BUCKS per successful new purchaser, but make sure: 1. You change the name for each new account. 2. You make the purchase within 72 hours from joining, no more.
