Overhere, you pay more for faster connections, and with some providers you pay more if you want a larger download/upload quotum per month (fixed monthly price of course in that case). But those count for the whole internet. they do not offer packages with a part of the internet, or things like that.
However, there might be something into really cheap (sponsored) packages that allow you to view only a few sites. Fixed packages (say, wiki and hotmail

), or free choice. I wouldn't have problems with such packages,
as long as a full internet access package does not become any more expensive.
