USPS Special Services

USPS Special Services can be requested using USPSProviderConfiguration.SpecialServices field:

    using ShippingRates.ShippingProviders.USPS;

    var configuration = new USPSProviderConfiguration(userId: "xxxx")
    {
        Service = Services.Library,
        SpecialServices = new SpecialServices[] { SpecialServices.SpecialHandlingFragile }
    };
    rateManager.AddProvider(new USPSProvider(configuration));

Please pay attention that Service should be specified explicitly and shouldn't be Services.All, Services.Online or Services.Plus. Otherwise, USPS will ignore special services.

1. If any of the packages have SignatureRequiredOnDelivery set then SpecialServices.AdultSignatureRequired will be applied.
2. If any of the packages have InsuredValue set then SpecialServices.Insurance, SpecialServices.InsurancePriorityMail, SpecialServices.InsurancePriorityMailExpress will be applied.
