Food Lion has just announced that they have updated their coupon policy. They are no longer allowing stacking.
They stated on their facebook page:
After reviewing our current policy, we are unable to accept multiple coupons on the same item or allow “coupon stacking” at this time. Because our company offers excellent prices on all of its products, we hope you will be pleased with your low, total grocery bill. We appreciate your patience as we reviewed this important issue.
You can view the complete policy at Food Lion. I suggest printing this and placing it in your binder as well if you shop Food Lion.
I just updated How to Coupon at Food Lion post too.
