Plus they already have an option for people who can't afford the cost of lifetime up front, it's called monthly service. The whole point of lifetime is that they are trading you an entire lifetime of service in exchange for you paying the whole amount right now. Allowing you to pay it off over time defeats the purpose and makes it a worse deal for them. They use to offer a yearly service contract that was like $100/year which was a savings over the typical $12/mo, but had no residual value like lifetime.
