Canon Refurbished store has the EOS T7i DSLR Camera with 18-55 IS STM Kit Lens for $558.99. Canon refurbs are usually high quality, low shutter count and practically indistinguishable from new.
The best deals for Canon are usually around Black Friday (printer combos) but this is a nice price for someone looking for a T7i. This camera is a step up from T6i as it supports more Autofocus points and Dual Pixel AF
A good companion for the kit lens is the Canon 50mm 1.8 STM (available for 100$ on the refurb store)
