I would have to work overtime for 215 days to save the money for that, even though my job in the Czech Republic pays 436.5Kč an hour, and I can save 10% percent of that. My buddy in Japan, bought one for ¥357014.83

It was just pointed out to me that in France, amounts are written with the Euro-sign post-fixed, like 2 927,10€ or 2 927.10€ or 2927,10€ or 2927.10€.`;
