I have written about ebates plenty of times. They pay you cash back for shopping online. If you didn't sign up for the $5 bonus, maybe a $10 gift card will pique your interest. I got over $35 deposited direct to my paypal account from my Christmas shopping, which is awesome for just doing what I would have done anyway.
So, join today and choose a $10 gift card to Target or Barnes and Noble, among others. You can still choose the $5 cash signup bonus if you'd prefer.
