I have clients in the logistics business and will drop them an email whether these guys are credible competiton, ok?
My impression though tends to be that these guys are not a scam but a network of independent smaller logistic providers working under the brand shp-westline, but retaining their repective individual legal status. Nothing too unusual with that. It used to be the way to do logistics business in Germany until the multinational logistics providers such as UPS, FedEx, TNT and Royal Mail started centralizing things via buying companies from the market. Or what the German Post did when it bought DHL in the US. These guys here want to remain independent yet offer a global brand. That doesn't mean their shipping service is less reliable.
But let's wait what my clients will have to say.
