Meijer Couponing Policy

I just want to update everyone about what is going on with Meijers. It appears as if they have changed their policy where you can not use MPerks and a manufacture coupon. Although, today I did self checkout, and I had both coupons and MPerks. I did my coupons first and then the MPerks and both applied. So I don't know what is what, but it appears that it is hit or miss. Usually the manufacture coupons are better then the MPerks, so that is why I put my coupons in first.
