Since I haven't been able to get these cereals on sale, I have been bidding using Priceline and paying around $2.20 a box (Complete Bran Flakes and Mueslix)...
How did you know that the cereal would have the special certificates on them? Once you bid and find out what store.....they might not have the miles promotion on them. I know they were hard to find in Houston. Were you able to specify that you would only purchase boxes with that marking?
