Hello, I'm using 1.6.0.9 ver. but I've detected big bug in discounts. In products i've added 15% discount from quantity 1, but of quantity is 20 it should reduce price by - 0,01 € ir 40 by - 0,04 € and so on. Product list show everyting ok. but cart don't reduce price by 15% just bys 0.01 if quantity is more than 20.. Does somebody know how to fix this?
