Problem

Will sell bulbs in the product module you can give a price for 1 item (normal)
but what if someone want to buy a thoussand i can get a lower price , how to do this.
Secon some bulbs have different size an differetn prices
example

tulip Darwin 10/11 1,00 euro
tulip darwin 12/14 1,25 euro
How to do this or is there a module that can do this

well discount price based on qty is included in the cart by default under the discount tab. But this doesn't discount options, so if you want that you will probably have to have a custom mod built.
