It might depend, for germany I have no problems with currency conversion and I think I would not have gotten anything from what I wanted cheaper anywhere else (World suite, Traveler....), all with combining 50 % off and the yearly voucher < 50 %. You have to look for the right moment of course (in the first year after buying falcon I dont waited for the right deals).If you are talking about the vouchers you get from uvi once a year for shopping at uvi's own site, they are not that generous, as it is always more expensive to shop there instead buying from other sites, plus the wrong currency conversion, so even with the vouchers it is more expensive to buy from uvi directly
