Going with the theme of the season, the official Canon USA Outlet store has launched a Pumpkin Spice Refurbished Sale (that’s their own name for it, not my goofy joke), and that includes two primes under $100 but still with a 1-year Canon USA warranty:

+ refurbished Canon 50mm f1.8 EF for $80

+ refurbished Canon 24mm f2.8 EF-S for $99.99 (thus my loophole to call it under $100)

The Canon 85mm f1.8 EF lens goes for $350 in new condition at authorized Canon USA that bundle it with some free accessories such as Adorama.

But if you are comfortable with manufacturer refurbished with a 1-year Canon USA warranty, you can get it in this condition for $260 for a limited time at the Canon USA store.
