exact same mag same upc number just a duplicate listing with a different model listed get the less expensive one

There's no difference at all. One is just older stock so the price change is due to stock on hand.

Howard, They are the same UPC code (the same magazine). Someone at Buds entered a MF43006 instead of the correct MF43106 and created two listings for the same Magazine. I would stock up on the current $19.16 priced magazine. (the price difference it likely due to a difference in stock level of each).
