I was shopping for another Canon 6D + 24-70 2.8 II zoom.
I priced it out on eBay, Greentoe (Andrew is great and very responsive, BTW) and CPW.
CPW came in @ $97 less than Greentoe, and $31 less than eBay grey-market sellers.
The invoice came from a VERY well known store, who is listed on Canon's USA authorized seller list.
So if you are doing some hard shopping because you are ready to buy, don't overlook CPW:
