Search any product on Bing.com . Follow instruction (trust me you will see lot of Bing cashback logos), buy item after open your Bing cashback account.
Once you have at least $5, you can request your cash back from Bing about 60 days after purchase (time varies by store) via PayPal, direct deposit to your bank account, or mailed check (Disclaimer - that's what I read).
PS. I have not used Bing Cashback yet (because I haven’t bought anything recently). Please post comment if you have used it.
