Tier prices can be attached to each option in a dropdown or color swatches. If you want to set tier prices for the entire option template regardless of the option, you can use "Global Tierprices."
These tier prices then apply to all products associated with this option template. The tier prices at the options can also be used in combination with the global tier prices. The prices are then simply added together.
On the option tier prices, there is also a button to load the globally defined tiers.
