1. They do give overage. So if your coupon has a higher value than the item, they have to give you the difference, either in cash or apply it to the rest of your items.
2. They WILL NOT accept a coupon that doesn’t scan. This is their new policy :(
3. They do price match. If you find a lower price elsewhere, bring in the flyer and they will price match it right at checkout. Bonus – you can still use a coupon on a price-matched item!
