DO your regular shopping through these sites and earn %'s in cash back! Plus several have 5.00 sign on bonuses. These are the only ones I can think of right now, these are awesome and each site has offers from different stores. Give em try!!
Ebates have a 5.00 sign up bonus.
Shop at Home also has a 5.00 sign up bonus.
Big Crumbs not sure if there is a sign up bonus or not.
