I did buy two of each and they still rang in as $2.07. I never even saw the add, just went off the post. I will have to take the receipt back. This was Monday Morning at the SF Albertsons.
My receipt also said $2.07. I finally figured it out. At the bottom is takes $1.00 off and says "Post" something. I'm sorry, I don't have my receipt to give you the exact wording. So- for 6 boxes is would take 3- $1.00s off because of the groups of 2 thing. $2.07 - 50 cents would be 1.57 a box. I hope that makes sense.
