title: Integrating Shipping with Ruby on Rails
body: <p>What is the best method to include shipping quotes in my cart?</p>
  
  <p>The basic flow of my site is that</p>
  
  <pre><code>1.) User selects products  
  2.) User is shown cart  
  3.) repeat 1 and 2 until User wants to pay  
  4.) collect user details ( email, address where items will be shipped to )  
  5.) make payment via active merchant  
  6.) order is submitted to distributor.  
  </code></pre>
  
  <p>I would like to insert a shipping information, so that the user can pay for his purchase + shipping costs via active merchant.</p>
  
  <pre><code>1.) User selects products  
  2.) User is shown cart  
  3.) repeat 1 and 2 until User wants to pay  
  4.) collect user details ( email, address where items will be shipped to )  
  5.) calculate the cost of shipment, add cost to cart, show to user;
  6.) make payment via active merchant  
  7.) order is submitted to distributor.
  </code></pre>
  
  <p>Is there a gem or plugin to help me here, if not... how can I get this done?</p>
  
  <p>Thank you<br>
