Basha's has Michelina's frozen meals for $ .50 right now. Under each one of the meals (underside of the lid) is a coupon Buy 2 get $ .50 off.
If these are doubled, that is free.
You can also print coupons @ http://michelinas.com/SaveMoney.aspx. These won't make them free and I am not sure if the variety matches with the ones that are not on sale. But it would let you get the first ones for cheaper before you take the lids off.
