Hi, I've seen a set on another retailer website that includes the 40mm Airwrap long barrel in the Dyson Airwrap Multi-Styler and Dryer Complete Long with Presentation Case Nickel and Copper. Same price as the Dyson website, should I go for that one as it includes more? Why wouldn't it be included on the Dyson website directly? Any insight would be great. Thanks.
