Did you notice in your Smart Source insert that KMart is doubling ALL Hasbro coupons?! This is great because you can score up to $10 off 1 game! (this promotion goes through 9/17)
I went ahead and got some prices at my local KMart (who had no idea about the sale–but I did bring my inserts showing the promotion)
I bought three games and was able to have all my coupons double–so I don’t think there is a limit on how many you can do in one transaction.
