title: Magento Bundle Product Custom Price Calculation
body: <p>I'm stucking on a problem with magentos bundle product prices. After hours of searching and trying I hope someone can help me out with this:</p>
  
  <p>I have bundle products with a base Price (ie: 25,- EUR) - this price is related to 1 Liter.</p>
  
  <p>The Options (simple products) have a base price too (ie: 2,- EUR) and a attribute called "fill_quantity". Here goes a Value like 250ml (0,250).</p>
  
  <p>The calculation (the final price in frontend) should be:</p>
  
  <p><strong>Bundle Product Base Price *  Attribute Value fill_quantity + Option Base Price</strong></p>
  
  <p><strong>iE: 25 * 0,25 + 2 = 8,25 EUR (final Price)</strong></p>
  
  <p>Thanks and regards
  Andi </p>
