You can either have this work with the customer clicking the Shipping Estimator button or to always show by configuring this in: Configuration ... Shipping Packaging ...
Shipping Estimator Display Settings for Shopping Cart
0= Off
1= Display as Button on Shopping Cart
2= Display as Listing on Shopping Cart Page
NOTE: a disadvantage to Always showing the Shipping is when using a shipper like UPS, USPS, FedEx etc. and the Real Time Quote server is down or slow ...
This would make your shopping_cart page delay or not display at all due to time out issues because the Real Time Quote server(s) have problems ... problems might be a 1-90 second delay, each, or not responding at all ...
NOTE: when a Real Time Server is down, you can always remove it until it is functioning again ... usually 3 minutes to 3 days ... :eek:
