Canon takes up to 50% off select factory-refurbished Canon EF lenses and Speedlites. (Discounted prices are as marked.) As most orders will be $100 or more, free shipping applies; for items below $100, shipping adds $11.99. That's tied with our mention from two weeks ago as the best discount we've seen on refurbished lenses at Canon this year. Note that stock is limited. A 90-day Canon warranty applies. Deal ends May 25. Some best bets, each price lows for its model with a Canon warranty:

• Refurbished Canon EF 75-300mm f/4-5.6 III USM Telephoto Zoom Lens for $159.79
• refurbished Canon EF 55-250mm f/4-5.6 IS II Lens (pictured) for $203.99
