From reading the comments, it appears that most of the prices on this website are wrong for most people. They might be taking either the worst-case price or the least value data plan (500MB starter plans) instead of the average data plan.
These cost analyses are always popular for people to brag about how much cheaper their country's data plans or broadband speeds are, but I seriously doubt that many Canadian Redditors are paying $0.17 for every page load. Simply browsing the front page and clicking on a few comment sections could cost $10 or more. Doesn't pass the sniff test.
