Accelerators -- unseen by the novice user -- may often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. Allow users to tailor frequent actions.

Since this page is unlikely to be used frequently there is not a strong need to feature accelerators.  The page is both flexible and efficient to use.

By allowing the user to continue with the address as entered, the page is being flexible in not forcing an address know by the system.

By offering a number of likely alternatives to the address entered rather than forcing the user to retype the address the page makes the user more efficient.

Dialogues should not contain information which is irrelevant or rarely needed. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility

No other user-supplied information about the package, such as the weight and dimensions, is included in this page as they are not needed here.
