I like this books! I want to get them but I do live in South America and those books are not sold here, I tried to contact the page one editorial to order them but they give me the price in Singapoure Dollars and I don't know how many it will cost, I searchead for them in amazon but them are so expensive! even the used ones sometimes cost much more than the new ones and I do not have experience in buying online, I wonder how many USD is 38.20 singapour dollars-
