Here in the UK,
Electromod seem to be the "official resellers" or something similar; I can't remember where I found the site so it may or may not be official. But they do sell all the Schiit stuff.
Prices seem to be about the same in £GBP as in the original $USD, i.e. Bifrost is $349 from Schiit direct or £349 from Electromod.
That's a fairly steep markup, depending on the current precise value of the £, and of course any resellers will be getting a vendor or price from Schiit rather than retail, but it's probably still fairly good value. I was considering ordering direct from Schiit but after international shipping, import duties/taxes and the shipping company's handling fee (since they pay customs directly and then charge you a hefty handling fee to do that), the price shipped internationally is probably higher than the local reseller's price anyway. Plus there's the issue of returns/support, and the Schiit is more likely to get damaged via International transit anyway.
Currently, according to
XE, $350 USD is £213.68 GBP (mid market rate), so Electromod are profiting approx. £137 for a Bifrost, plus bulk/vendor discounts, minus shipping/import fees/etc.
Interestingly, until recently the Magni/Mode were each just £90, I've been waiting and saving to get one of each plus the cables, but when I checked just now my original links didn't work (they seem to have had a site redesign, or at least moved their items around), and they're back up to £99. Disappointing, hopefully that's to cover higher import costs or lower vendor discounts rather than just skimming extra profit from their customers.
