Back on topis, as interesting as the video is, it shows a real lack of knowledge when it comes to BI methods and multi national business practises.
Im pretty certain that a company the size of GW does actually use BI tools to study the sales trends. They will know with some certainty if the US online sales embargo has actually affected number of sales. Only they will be in a postion to say if it is a positive thing.
The other thing he mentions is the exchange rate. I think that it is more complex than he makes out. If GW could sell at a uniform price across the world, Im sure they would, as it would be so much easier for them. Different countries have different taxes and also different related costs. My understanding is it is muchmore expensive to run a B&M shop in Australia than it is in say the North of England. You therefore need to sell at a higher price to cover costs.
Your toast has been burnt and no amount of scraping will get rid of the black bits.
