"Features" are treated rather strangely in MyPlan and I find it confusing. They aren't added to the big bold "Your MyPlan" total price and only shown in the details at the end. But more importantly, why don't they count against the total for subsidies? I also assume they don't count towards the minimum cost needed for certain bundles? If it were a true build your own plan I'd expect and want to be able to swap a feature like voicemail in and swap out some voice minutes.
