Lol haha. I don't know any current promotion going on for this, but I know kellooggs do promotions on their brand often. Special k cereal and jeans etc.
I used to keep proof of purchase of everything, but I am not as organized with others here, so the clutter drove me nuts! Saving box tops is enough hassle for me. LOL not to mention having to rescue them when one of my family member finished the box before me and about to throw them away...
And pampers and huggies codes. I mentioned that those diaper packages has codes and box tops, so my husband started saving the whole packages of STORE BRAND diapers for me not knowing the difference. LOL
I won't even try explaining which brands has box tops and codes inside and what to look for. I just thanked him and threw away the packaging. LOL
I try to cut off what I need and store them as soon as possible now for items like box top from huggies. Speaking of which, someone wanted my box tops and I an suppose to be counting them.... Better get that done while baby is sleeping.
