Hi,
I work on a 1.6.0.9 install with default template, b2b with 4 categories of items, no guest checkout.
Whatever rule I try (discount in customer group or catalog price rule attached to customer group) it seems that only the default customer group of the customer is retained for the finding of the price.
This would mean that I will have to create for every combination of category access / discount a new customer group ???
From some older posts I understood that the various discount rules were combined, but I could not find why or when this changed.
Maybe someone could point me to the file (and some idea how to modify it) which needs an override in order to combine the rules for all customer groups to which a customer belongs?
