If you want to add wholesale price and you want to do some calculations on total price to change subtotal, than follow below steps:

Step1: Create one attribute `wholesale_price` .

Step2: Add getWholesalePrice() function defined bellow in


public function getWholesalePrice($pID)
$_product = Mage::getModel(‘catalog/product’);
return   $_product->getResource()->getAttribute(‘wholesale_price’)

Step3:  Open file yourproject/app/code/local/Mage/Sales/Model/Quote/item.php

Add below line in   function setProduct  ->setWholesalePrice(Mage::getModel(‘checkout/cart’)


after ->setCost($product->getCost()) statement in function

Step4: To change subtotal open below path file


public function collect(Mage_Sales_Model_Quote_Address $address)
* Reset subtotal information

* Process address items
$items = $address->getAllItems();
/*******Start:: Changes  for wholesale price calculation********/
$isWholesalePrice = false;
$finaltotal = ”;
/*******END:: Changes  for wholesale price calculation********/
foreach ($items as $item) {
if (!$this->_initItem($address, $item) || $item->getQty()<=0) {
$this->_removeItem($address, $item);
/******START:: Changes  for wholesale price calculation*******/
$_totWholesalePrice = $item->getWholesalePrice() * $item->getQty();
$_totPrice = $item->getPrice() * $item->getQty();
if($_totWholesalePrice >= 500 || $_totPrice >= 1000)
$isWholesalePrice = true;
$finaltotal += $_totWholesalePrice;
/*******END::Changes  for wholesale price calculation*******/
/******START::Changes  for wholesale price calculation******/
/******END:: Changes  for wholesale price calculation********/

/*** Initialize grand totals***/



return $this;

Explaination of above function:: In above function we changed calculation of subtotal, here condition is if total wholesale price(wholesale price *  Qty) of any product is more than 500 or total price(Sale price * Qty)  is more than 1000 than subtotal is calculated on wholesale price.

Above four step will help u to change subtotal and grand total according to subtotal for only one page checkout. To reflect the above calculation to multishipping than follow step5also.

Step5: Open file /yourproject/app/code/local/Mage/Sales/Model/Quote/Address/Item.php

Add below line in   function importQuoteItem


after ->setPrice($quoteItem->getPrice()) statement.
