I don't think it is worth spending $4.00 per box unless that is what you planned to spend anyway for that particular box of cereal. This promotion will be here for awhile, and Kelloggs does put their cereals on sale periodically. So it takes patience. To spend $4.00. you could spend that kind of money and actually fly somewhere and get those miles. It only pays if you can get them cheaply. The sunday papers have coupons, and dominicks also gave out a $2.00 off for 4 boxes of cereal. I think patience is the key. Just think, the $500 tax deductible donation (amounting to about $360 after taxes depending on your tax bracket)to WWF that clickrewards had (expired March 31) gave you 20,000 click- rewards. 10,000 of those could be converted to 20,000 starpoints. 20,000 starpoints could be converted to 25,000 miles (with 10,000 still remaining in the clickrewards account). That's 35,000 miles for $360 which would only buy you 90 boxes of cereal (at $4.00 each) for 9000 miles. So, there are better deals around unless you have a good use for the cereal AND you get it cheaply.
