Well, learned how Kmart deals with overage today. Went to the Salem Kmart and got the last 5 boxes of Motrin PM 20ct they had. Used (5) $3/1 coupons and the total came up to -$1.55. The cashier hit cash/tender on the register and it prompted her to give me $1.55 back in change!!! Never in my life have I walked out getting actual money like that!!!!
