Why dont you just go to a friend's house with internet connection and download it. Its easy to set up, etc. If you have good relationship with game shops, you can try as well.

Basically any household with a decent connection will be good enough. Or if you have an high capacity mobile plan, just hotspot your phone and download.

Physical discs still requires you to have the disc inside to play. So you still need to buy them. You cant download and then play without the discs.
