The equations may make sense, but that doesn't mean customers are happy with adjustment. The on the official Netflix blog is already filled with irritated comments.

"I've been holding off investigating alternatives, but now that this price hike is going in, it's time to look at what else is out there," one user says. "Will my extra money guarantee that I won't wait days/weeks for a new release Blu-ray like I do now?" asks another.

Other commenters suggest the amount of titles available isn't high enough to warrant the change, noting that they often receive DVD even when requesting Blu-ray due to limited stock.

Should You Switch?

So, the big question: How do the adjusted costs stack up with Netflix's main competitor, Blockbuster? The simple answer is that it depends on how much you're renting. Blockbuster does automatically include Blu-ray access within its base prices. Still, in some cases, Netflix will remain cheaper -- even with the upcoming change.
