Hi and welcome - they sound like a bonanza deal to me, they cost considerably more to dealers at wholesale price (i.e. over 25 cases) to start with.
It's hard to compare our prices to US ones because of the postage costs involved of importing boxes, not to mention the 17.5% tax plus the administration charge £8!
WOW! I'm always amazed to see the duty you guys pay in the UK. We have it too, but it's on luxury items like jewelry, tobacco, perfume, cars, booze, silk, fine porceline, etc. None on printed matter. Cards are printed matter. And an administrative fee....geez, don't your taxes pay for keeping the government running?
