title: Magento - How to set minimum amount of products per order for a category?
body: <p>Is it possible to set the minimum number of products required for a category per order in Magento. A client sells wildlife paintings, one of the shop categories is 'cards', it isn't very cost effective to ship less than 6 of these at a time.</p>
  
  <p>How would I force a minimum of 6 products from the cards category?</p>
  
  <p>Thanks,
  Dan</p>
