I just did my first "real" attempt at some couponing, mostly with internet coupons, and discovered a small problem..
I had a "Cheerios" coupon scan against a box of Golden Grahams (which was fine with me), and then a "Total" coupon scanned against the Cheerios! Leaving me one coupon short in the end, because my second Cheerios coupon wouldn't scan against the Total
Anyway, is this fairly normal? Is there any (fairly simple) way to tell if a coupon that says one thing actually works on a family of products?
(btw, my trip total was $30 for $64 total value, so I'm still pretty happy, given that it was stuff I actually needed

)
