As for the macaroni, I would bet that list should have been 24 boxes at $32.99 and Amazon is selling at $30.86 for 24. If you look through the other listings the degrees of error are similar. Amazon is using a digital file of prices supplied by vendors or a 3rd party to provide cost comparisons. The error lies in either a unit of measure or a decimal position discrepancy between the sending and receiving parties' understanding of what the digital data mean. The person talking about algorithms is not far off although it's probably a much simpler situation. One of the 2 sides has to change his view. Rather than emailing customer service which will never get to the proper area in IT, try contacting Jeff Bezos. You all are clever enough I am sure there's a way.
