Lowes Foods is in the process of making changes to their coupon policy including clarifying their acceptance of competitor's coupons. I have spoken with the corporate office and they indicated that the changes would be posted in the "near future" on their website. They will also be announcing the changes on social media.
At this time, they are not releasing the details of the changes. They would only say that they were clarifying the current policy of accepting competitor's coupons, among other things. That could mean that they will specify which stores they will accept coupons from, that they will begin taking coupons for specific products (not just for a total off your total order), etc. At this time, we just don't know.
You can see the current Lowes Foods coupon policy at LowesFoods.com.
Once they post the new policy, I'll be sure to update everyone here on the blog.
