Meijer Trip 7/20 paid $9.90 and received $7 back for my next purchase!

So I ran to Meijer yesterday and bought the above for $9.90 and received $7 back from 2 catalina coupons that I can use on my next trip. Here's what I bought and the coupons I used:

(Meijer has a promo, that if you buy 10 listed items for $20 you will get $5 back for your next order)

2 Bisquick Mixes $2 each -used (2) $.60 from 5/31 ss

3 Fiber One Yogurts $2 each -used (3) $1 coupons from coupon bar to the right, coupons.com

1 Fiber One Pancake Mix $2 -used $.60 from 7/19 ss

2 Pillsbury Premade Cookies $2 each -used (2) $1.25 coupons from here

2 Boxes of Chex Cereal $2 each -used (1) $1 off 2 from 6/14 ss

My total after coupons was $9.90 and I received a $5 catalina coupon back for buying 10 of the items listed in the ad under the 10 for $20 promo AND I received another $2 catalina coupon, I think it was from buying the yogurt, but it didn't tell me on the catalina coupon.
