Canon takes 15% off all factory-refurbished Canon lenses and flashes, with no coupon required. (Prices are as marked.) Plus, orders of $100 or more can get free shipping via coupon code "SHIP712", otherwise shipping starts at $11.99. That's one of the best percent-off deals we've seen on these refurbs from Canon in recent weeks, although we saw 20% off in July (since expired). Sales tax is added where applicable. Coupon expires August 31. A 90-day Canon warranty applies.

A best bet is the the factory-refurbished Canon EF 50mm f/2.5 Compact Macro Lens (pictured), model no. 2537A007AA, for $203.99 with free shipping via the above coupon. That's $68 under the lowest total price we could find for a new unit elsewhere. This lens has a 50mm focal length and allows focusing from infinity down to one-half life size.
