We have a Magento set at applying TAX per item - then totaling the cart value. This helps greatly with rounding issues.
This does not seem to be calculated this way with bundled product additions to a product.
ie, I have a product that is 9.50 including Tax I add an item (Custom option) that is another product with a price of 1.99
I would expect a total of 11.49
But, it is showing as 11.50 in the cart. It seems to adding the 2 ex TAX values together, then adding tax and totaling.
How can we set the adding of a item to an existing product to follow the same rul of apply Tax to items first - then total ?
