Amazon offers its Prime members the Hutzler 571 Banana Slicer
with free shipping
. (Non-members can spend $25 or more to get free shipping; otherwise it adds $5.74.) That's $2 less than our January mention and the lowest total price we could find, again by $2. Sales tax is added where applicable. It's dishwasher safe and spares you from the labor-intensive task of slicing bananas with a knife.
