What do you think? Is this a case of

  1. Asymmetrically Dominated  Option (Decoy pricing) to make it attractive to buy the middle option?
  2. Effective non-linear pricing to capture more value from those who want 3 baskets (like what we saw with hair-braiding case here)
  3. Deliberate mis-pricing to capitalize on those customers not so good at math?
  4. Deliberate pricing (with the separation of price postings) to capture consumer surplus?
  5. Math error by vendors compounded by customers’ reluctance to do the math?
