US Amazon only lists one size at 135 x 130 x 190mm and 68g, so the ones you linked might be erroneous. I think it's also possible to buy it digitally, if you like to read books that way, but I'm not sure how or where.
Ckecking some random-ish countries, in the US and Mexico it costs (without shipping) between $4.3-$4.5, and in the UK about $6, so the website you just linked to might be ripping you off. Since you're buying it online from a country where you can't find it, shipping is gonna screw you over anyway, though.
