A few weeks ago, Nabisco made available a $55 back-to-school savings booklet. I just received mine in the mail, and besides the coupons, there are two $20 mail-in rebate offers. One is good from now until 12/31 andthe second is good 1/1/10-6/30/10. For both, you buy 10 Nabisco cookies and crackers, 5 Kool-Aid Jammers or Capri Sun, and 5 Kraft Easy Mac single cups. I do not believe these need to be in a single transaction because each form says to mail in your receipts with prices circled.
I am mentioning this now because if you sent away for the booklet but haven't yet received it, you can still start looking for coupon matchups to make this deal worthwhile. For instance, Meijer right now has Capri Suns on sale for $1.65, and when you buy four you get a $3 catalina coupon. Meijer mealbox also has $1/2 Kraft Easy Mac coupons.
