We are encountering a strange miscalculation with our shopping cart price rules.
We have two price rules. One is standard 3% discount for logged in customers and one is 2% additional discount when choose for paying with direct debit.
The standard 3% discount is calculated correctly but when the customer chooses to pay with direct debit Magento calculates about 4.3% instead of the proposed 5%.
Has anyone experienced this before?!
