So in the coupon center of your just for U account, there should be a $2/1 McCormick spices coupon to load. That's a store coupon, so you should be able to also use the $0.75/1 from the 3/3 RP to get $2.75 off of each spice. What gets even better is the basic spices are on sale for Buy 2 Get 1 Free! The limit on the jfu offer is 2, so get 2 at the cheap price and get the 3rd free!
As you can see in the picture above, they've got spices as low as $1.99, so they would be free!
Also, the Seattle's Best coffee is unfortunately not included in the buy 4 save $4 promo.
(Thanks, Mashup Mom!)
