You need to spend $15 before coupons to receive the $5RR.
You can buy 10 jars for $1.50 each and use 5 $1/2 coupons.
The cost would be $15 - $5 in coupons= $10.00, and get back $5RR, for a net cost of $5, or $0.50 a jar. This seems like a good price, I don't use this product personally.
One problem could be that your store will not have 10 jars of Ragu, then you would have to buy another qualifying item.
