Hi Clint
The functionality of special pricing is a subset to that of alternate price lists, and except for one scenario, I never recommend using special pricing. I always do everything in APL's, which are much easier to maintain, can be shared by multiple customers, and can have fractional pricing and alternate item descriptions.
The one scenario is if the price of a whole category of items is a percent of or fixed dollar adjustment to the base price. Then it's easier to use special pricing.
So why can't you just do everything using APL's? If there are two APL's for one customer, it's easy enough to override the price list when entering an order, although I'd be surprised if they couldn't just be combined into one (can it possibly be that the same customer buys the same item at two different prices?).
