Excellent reply to a useless response from support. This is a serious problem for a lot of people. How can this still be an issue? Having to manually change pricing on every other invoice is getting seriously old. This should be a top priority as this is used by MANY people. How hard can it be? If customer = distributor use this rule. If customer = wholesale use this rule. Come on guys! This has been in beta for almost a year now and its a feature we already had. Please put some effort into this one.
