Goodmorning, we have a problem with the calculation of the total price in the cart.
We have products with different color (as attribute) and tier prices for quantity.
For example:
0-100 price = 10€
101-200 price = 8€
201-500 price = 6€

When we add the product into the cart selecting 100 for each color, we need that the price is related to the sum of the quantity for this product in order to get the correct tier price.

Example:
product 1 (blue) qty 100
product 1 (red) qty 100
product 1 (Yellow) qty 100
total qty for product 1 = 300
so the unit price must be 6€ (201-500 tier price)

Is it possible?

Thanks in advance,
Paolo
