First, are you using the real-time shipping options that get the quotes directly from the carriers (e.g. USPS, FedEx, UPS, Canada Post, etc.) You can view those settings by going to Commerce Setup > Shipping and then look in the "Shipping Carriers" section (not the "ShopSite Shipping Rate Calculations".)
If you are getting real-time quotes then those are the correct rates. You can add other options like two-day or overnight delivery if you shoppers want to pay for quicker delivery. Also, make sure you have specified the correct weights and sizes for the products that you do ship so that the rates are as accurate as possible.
