The best way to learn multi-channel marketing and eCommerce is to simply do it! I built an eCommerce business under the 3Gstore.de brand, quickly becoming Germany's second-biggest seller of iPhones in late 2008, opening brick & mortar stores in Berlin and Bochum in 2009. How? Listening and offering what people really wanted: the (brand new and then revolutionary) iPhone 3G without simlock and forced contract on the T-Mobile network. Our biggest coup? Suing T-Mobile for their claim to offer the iPhone 'exclusively' on their network, which got us coverage on the frontpage of the german Financial Times... The end? After the T-Mobile contract ended and Apple themselves started selling unlocked iPhones to all vendors, I sold the remaining assets to a chinese investor in late 2011. All 3Gstore blogposts.
