A few days ago, the blog about the book "Looking for a challenge 2" was posted on Codeforces, I read a quarter of the book and found that the quality was really good. I talked with a few friends about the book and we decided to buy a "Looking for a challenge 1". At first we considered buying a paperback version, but it was quite expensive and I'm afraid that some problems may occur during the shipment from Poland to China.
After a few days I found the book "Looking for a challenge" was available on the website "http://ibuk.pl" for 66,50 zł, the cheapest I can find on the internet. Although I can't read Polish, I used Google translate to buy the book. So I purchased the book with a master card, and I was able to download the pdf version of the book. With the excitement, I started to download the book. The internet speed was about 100 Kbyte per second, and the book was about 60MB. I thought that was too slow, so I changed the network connection a few times and refreshed. After that, I found that I reached the download limit, and was not able to download anymore.
So, the situation was I spent 66,50 zł (about 17.5 US Dollars) for nothing, since I can't download anymore and I never finished downloading. I was really depressed since it is quite a large sum of money for me, and that I still don't have the book. I tried to e-mail the website (using google translate, of course). I figured that there may be Polish participants on Codeforces who knows about the website ibuk.pl or similar situations, so I posted this blog to ask for help. What should I do? Is it likely that the website will let me download again or send me the book?
