Canon takes 50% off a selection of refurbished telephoto zoom lenses, as listed below. Better yet, all orders qualify for free shipping. That puts each at least $109 and as much as $339 under the lowest price we could find for a new model. Some best bets:

• Canon EF 75-300mm f/4-5.6 III Lens for $79.99
• Canon EF-S 55-250mm f/4-5.6 IS II Lens for $119.99
• Canon EF 70-300mm f/4-5.6 IS USM Lens for $259.99
