I'm designing a CBC with a price that is tied to three other attributes. The price attribute itself has 5 levels (-40% of base price to +40% of base price). Between the tied attributes and the price level fluctuation, there is a total of 375 price point combinations that might appear.
My concern is that there are too many price point combinations to produce reliable simulations. I know that the price coefficient will simply be a function 5 price points (i.e., how respondents respond to "Price 1" vs "Price 2" etc.). But in reality, respondents will see each actual dollar value price point very few times.
