Olympus seems to be giving rebates on a number of MFT lenses. The rebates
appear to be either through the Oly site or through bricks-and-mortar stores
(not always the same lens). One example, the 40-150 R can be had in stores for
$99 -119, though Oly shows it as $199..
Wonder if they're trying to reduce stock before something new comes out?
