Feature: Auto-fill phone number on step 4

Scenario: Pre-fill phone number field on return visit
Given I am a logged-in user
And I have previously submitted a bag for sale
And I entered my phone number in the submission form
When I go to http://saclab.com/sell to submit another bag
Then the phone number field should be pre-filled with my last used phone number

Given I am a logged-in user
And I have never submitted a phone number before
When I go to http://saclab.com/sell
Then the phone number field should be empty

Given I am a logged-in user
And I submit a new bag with a different phone number
When the submission is completed
Then the new phone number should replace the previously saved number for future autofill
