title: Dimension based shipping in Magento.
body: <p>I need to calculate my shipping based on dimensions. Some of my items are less than 2 pounds but are larger in size.</p>
  
  <p>I googled and found a $240 extension for this but it's too expensive.</p>
  
  <p>Is there any alternative where I can send dimensions to UPS, USPS and Fedex and get the shipping rates from them in my Magento store?</p>
