Giving a specified discount on a product when ordering more then 200,500

Question

I don't know if there are any Ubercart guru's out here, but here's my question:

I'd like to give discounts to customers who order more then 1 of the same product.

Lets say the prices are as follows:

1 product - $5 each
< 10 products - $4.50 each
< 100 products - $4 each

Anyone knows how to realise this? I thought of adding my own custom price fields but i wonder how to call on them in the cart /checkout.

Answer 1

How about the uc_bulk_discount module?

Answer 2

I'm no guru, but some googling pointed me to hook_uc_price_handler.

You can set up a handler to deal with the price.

If you had a custom module called 'example' you could do the following;

function example_uc_price_handler() {
  return array(
    'alter' => array(
      'title' => t('Quantity price discount handler'),
      'description' => t('Discounts the price based on quantity ordered'),
      'callback' => 'example_price_alterer',
    ),
  );
}

function example_price_alterer(&$price_info, $context, $options = array()){

    if($price_info['qty'] > 200){
        $price_info['price'] *= 0.8;  //we're reducing the price by 20% as a demo - add your logic here 
    }

}
