Posted: Tue Mar 18, 2008 10:40 amContractual agreements with the various service providers currently prohibit ShopSite from showing rates for UPS, USPS and/or FedEx at the same time in the shopping cart. That is why the options are mutually exclusive in the ShopSite shipping configuration. You can use any of those options and one of the ShopSite shipping options (weight, currency, base etc) and you could configure them to have any name you want. Also in a Pro level store there is a custom shipping addon configuration option that you could enable and use a third party api for one of the options.
