Yep, got myself one of those for my 2nd wheelset and it arrived yesterday. in retail package. shimano items are usually excluded from coupon discount.
I got the 11-40 because i already have the 11-42 and I want to see if that will fix my weird cadence issue on climb. (sometimes i found myself right in between cadence, either too fast or too slow), but don't know if i can handle 40t *only* ... haha :p
