There are two good coupons to check out:
$1/2 Athenos Greek Yogurt. I have seen this several times for $1 each- so .50 each for Greek yogurt is a fantastic deal.
$.50/2 Plum Tots baby or toddler food. I used to buy these for Maya. They are perfect for babies that are learning to feed themselves. Maya used to squeeze the little packets herself. I have seen these for about $1 per packet as well.
Where have you seen the Plum Organics for $1? The cheapest I have seen is $1.29 at Target dropped their price since they started carrying a cheaper brand as well.
