Hi,
We have a customer that runs an art gallery.  They have to add a tax of 5% to single paintings that exceed kr. 2000 in price, but not to say, books.

So the shopping basket may look like this
Painting A - kr 2500 (fee must be added)
Painting B - kr 1900 (no fee)
Book A - kr 2010 (no fee)
Book B - jr 350 (no fee)

Using the discounts module I have set the sales discount to (minus) -5% which generates the tax, however this is applied to all products.  I have tried the various Discount types, but none seem to have an obvious solution to the problem (short of manually adding one and one product to a list that should include this tax).

Am I missing something, is there a workaround or do we need custom code?
