I think that BeFrugal is the best the best rebate site going. It very often has the best cash back rate of the competing sites. It is my go-to site whenever I shop online. The Firefox Addon is a real plus as I can get the cash back rate on the site, where I'm shopping, without going to a separate tab to log in. The only recommendation I would have is to have a periodic process to send the rebate check, similar to Rakuten. Other than that, I love the process.
