Are they celebrating the firmware update? I don't know, but these are awesome deals.
The Canon Store
has a couple of refurbished EOS 80D bundles for only $699.99.
Decide if you want the telephoto zoom lens or the flash.
The telephoto lens kit was originally $1,319.00 and the with-flash kit was originally $1,259.00.
Canon EOS 80D, EF-S 18-55mm IS STM Lens, and EF-S 55-250mm IS STM Lens Bundle
Canon EOS 80D, EF-S 18-55mm IS STM Lens, and Speedlite EL-100 Bundle
Again, these are awesome deals. Canon USA's refurbished gear is like-new and comes with a same-as-new warranty.
