From my experience, Albertson's does not allow overage. The coupons will beep & then will be adjusted down. Happened to me with the Mentos when they were .88 & the coupons were for $1. Free is still good though!
This is generally true and appears to be a policy across the board.
I got overage on the small steps 2 days ago. I had even told her that she may need to adjust them down and she got the managers key and pushed them through.
