Anyone know where I can get a coupon for a prescription?

I know many pharmacies offer coupons if you bring them a new or transferred presription such as Target,CVS, Rite Aid, etc. Usually they will give youa gift card for or say, when you fill a new prescription with them. Anyway, I recently filled a prescription at Kroger and was told that if I had a coupon from a competitor they would accept it ( I know Target had a gift card coupon in the paper this week but I missed it) Does anyone happen to have one or know where I can download or print one online? I did a search and all I found was expired coupons, I need a current one, please help,I only have a few days to find a coupon so that i can go back to Kroger and get the price adjustment/gift card/etc. Thanks to anyone who can help.
