In some cases importing from abroad will cost you more:
Shipping costs
VAT (and even in cases where the place you order from, e.g. B&H, which do not apply VAT on your initial payment and delivery cost, the shipping company, e.g. DHL, UPS, etc., will apply the VAT when they send you a bill later and I've found that this can sometimes be more expensive). For example, I've ordered some stuff from B&H and had them shipped to my home in Switzerland because the US prices are cheaper even after taking shipping costs and VAT into account, but still the bill I get from UPS for paying the VAT/Import taxes after delivery is higher than expected because they also add the processing fee/service charge as they pay the VAT/Import tax at the customs for you when it arrives and sends you the bill to pay them back for it later.
Sure the 150~GBP VAT on CVP looks high, but if you take into consideration other stuff it can be somewhat cheaper. Unless of course there's a coincidence that you're traveling to Geneva for some event and you're already spending money for that trip, in which case someone like me can order from CVP and hand it over to you here and you pay me back (which is going to cost you about 688.89GBP for the product, about 20GBP for the shipping, and about 50GBP for the VAT that DHL will bill me later, totaling around 760GBP).
