title: Magento: Fixed Amount Discount For Whole Cart For Percentage?
body: <p>It says on the Magento website that the 'fixed amount discount for whole cart' applies a percentage discount to the whole cart.</p>
  
  <p>This is not the case. For instance, if I type in 10, the whole cart value will be reduced by £10/$10.</p>
  
  <p>Is there any way to apply discount percentage to the whole cart?</p>
  
  <p>I know I can apply a percentage discount to each unit in the basket, but I want to be able to provide a coupon code to reduce the entire cart by x%, not the pre-VAT product prices.</p>
  
  <p>I'm using 1.7.0.2</p>
  
  <p><em><strong>EDIT:</em></strong></p>
  
  <p>I think it will be useful to provide an example of what I'm trying to achieve. So, I want to be able to provide people with a coupon code for 15% off the total cart price, after all other discounts have been applied.</p>
  
  <p>For instance, there is currently an offer for 3 items for £22. I want to then reduce the total cart price by 15%, to £18.70.</p>
  
  <p>Any help would be a godsend! Thanks in advance!</p>
