Open-box Canon 40mm f2.8 Pancake for $119 w/free S&H

Not as fragile as a pancake but more sensitive to syrup, pancake lenses are one of the lower risk type of purchases if you want to go the open-box or used/refurbished route. Which brings us to the Canon EF 40mm f/2.8 STM Pancake Lens available in open-box condition for $119 with free shipping and the full 1-year Canon USA warranty at Adorama as one of their many clearance items.
