I pay $55 Canadian for speed of 30mbps and 400gb bandwidth.
Do you have a generous friend with fast internet and lots of bandwidth that you can bring your PS4 over to download the entire thing?
All but one person I know (who downloads enough for me as is) have data caps so it costs, 50gb is worth a lot here and I don't ask for money.
