Sorry I didn't find this sooner because I think the buy 10 get $5 off ends tonight but there is a MQ for .50/1 chex mix and a MQ for .75/2 BC brownie mix King soopers (at least in littleton, co) rounds the coupon up to $1!!

long story short it boils down to chex mix for .50/bag and .38 for Brownie mix!! you just have to buy 10 (mix and match).
