where to buy?

Since I now am a proud owner of the 5D Mark III with the kit 24-105 lens, I always liked ultra wide angle landscape and city photos. Used to have the Canon 10-22 and recently with the OM-D the 9-18.

I would like to add the Canon 16-35 f2.8 lens to my "Kit" I bought my camera at Frys 1. b/c it was a great deal, 2. if I have to exchange it for a fault its hassle free.

Now with the lens, I am not certain if I want to pay the extra sales tax and if there could potentially be something wrong or go wrong with it? B&H or local store hence Frys?

Where do you buy and whats your experience for lenses? Thank you.
