My 1st Kmart double coupon experience

I have not taken advantage of Kmart's double coupon until today because their system have not been updated to accept the new GS1 bar coded coupons and it has been a hassle in the past, until today. I wanted to use a $5 rewards card I got an email for about 2 week ago here's what I bought & was happy.
