Giant: General Mills Catalina Possible Double Dip

I'm heading to Giant this afternoon to see if this works:
 
Buy 4 General Mills Snacks and Get $4.00 Catalina stacked with the Buy $20 and Get $7.00  Catalina.
The Betty Crocker Fruit Snacks and Nature Valley Granola Bars are both part of the double dip.

Here is what I am hearing from some of you:
Buy (4) Betty Crocker Fruit Snacks $8.00

Buy (2) Betty Crocker Potatoes  $2.66
Total $20.66 after coupons
use (2) $.50/2 Printable Betty Crocker Fruit Snacks Coupon
