Looks like this one is gone now.
Buy with Me, a daily deal site much like Groupon, is offering a free $10 credit with sign up. You must sign up through this link to get this credit. After you sign up, you will see your credit under “my account” and “credits+referrals.” You can choose to use it now or save it for any other deal later.
This just worked for me, but I do not know how much longer it will last.
