Netflix hadn't hinted at any upcoming plans to change the services it offers, but NewTeeVee spotted an unadvertised DVD-only plan on its site a few days ago, and an anonymous tipster from within the company indicates that's just the start. The DVD.Netflix.com page offers unlimited DVDs by mail, per month (one at a time) for $7.99, which slots it between the standard DVD & streaming combo plans and a $4.99 offering that gives just two DVDs per month. According to the tipster we spoke to, Netflix is planning to change its pricing entirely, by also implementing a streaming only plan with no discs for $7.99, and jacking up the minimum pricetag for combined services to $15.98 from the current $9.99 it has charged since November. They indicated the change would take place tomorrow night around 9 p.m., with customers notified by email and no plans to grandfather any of the old pricing setups along. With aggressive expansion plans pressing forward and its costs to acquire content rising sharply, hiking the price by 50 percent on many of its 20 million+ subscribers could be the easiest way to make the numbers add up, it could be just those subscribers who are left to determine exactly what Watch Instantly streaming (or DVD access) is worth to them.
