Q. Can I use a coupon that I found outside of Mr. Rebates?
A. No, most coupon codes you find outside of Mr. Rebates will void cash back on your purchases or negate the cash back tracking. With that being said, there are some merchants that may allow the "stacking" of coupons and cash back but we certainly advise our customers that using coupons from outside sources will void the cash back per our Terms and Conditions.
Your best bet is to use any coupon displayed at Mr. Rebates as those coupons are specifically approved for use with Mr. Rebates and will not affect cash back.
