Quantity discount problem (1.5.6.4)

Hi,

I have the following problem, is there any extension to resolve this?
So.

I have a product with quantity discount, for example:

Product A
1 piece: 10 USD
2-4 pieces: 8 USD

Product A has product options. For example: red color and blue color.

Customer put 1 piece of Product A with red color to the cart. The store show 10 USD price for it.
Customer put an other piece of Product A with blue color. The store show 10 USD price for it too.
But on checkout page, the store compare 2 x 8 USD price, because there are separately, but same product in the cart.

I want to the following:
If the cart contains: 1 blue Product A and 2 red Product A in the cart, I want to calculate the price:
10 USD for red
and
2 x 8 USD for blue.
(the 3 product is same, but other variants)

How can I do this?

Thanks,
Szilard

Hi Ernie,

I check this, but I want another things. So. This is what I want:

If the cart has two of the same products, but with different product option, the discount need to calculate like if this two same products are different.
So, 1 red apple + 1 green apple is not 2 apple with discount price, but also this is two separate apple with original price.
But 2 red apple has discount price.

2 red apple + 1 green apple: The two red is discount price, but the green is original price.

In this situation there is only one product, the "apple", with original price and quantity discount price. So, I need to reset the quantity discount on different product options.
