Following the moves of companies such as Qwest and Comcast, Windstream this week has launched a price for life promotion that locks down your monthly rate if you bundle at least two services (bundles start at $49.99). Windstream tells us the deal doesn't require a long-term contract. As we discussed when Qwest launched such a promotion, such deals often aren't worth it to consumers. What seems like a good deal today quite often isn't a good deal down the road, and in many instances customers can get better rates by renegotiating their rates with their carrier. Being civil, but threatening to take your business elsewhere can usually net you more savings than these price for life promotions.
