Ran to Target and found an endcap in the grocery section that had clearanced cereal on it.
Trix was priced at $1.44. They also had Boo Berry and one other one that were priced around $2.50.
You can get the Trix for under a dollar a box with the right coupon:
Buy 2 Trix $1.44 x 2 = $2.88
-use coupon for $1.00 off 2 select General Mills Cereal (found here)
Final Price: $1.88 for 2 (or just $0.94 a box)
