Air wick I motion air freshners at Target

As of this afternoon, the Target on Emerald and Milwaukee had 10 or so still in stock. They are located on an endcap toward the vacuum supplies and things like that. When I tried to purchase them the cashier said it wouldn't accept the coupon because it was more than the price of the item. After i made my other purchases, i went to customer service to see if they could explain it to me. They tried it again and it worked for them, but we had to ring each item up individually. The cashier told me, "When people are kind we really try to help them and get things working for them."
