If I interpret you correct, there is two main paths to do a price list:
Price Range. Which will at some point create a matrix of hundreds cells and buying 9 pcs can be more expensive than buying 10 pcs.
First Following. For each product there is one start price (normally high) and one following price (normally very small). Like $100 for the first item and $1 dollar for following items.
First-Following makes it simpler to both calculate and present in a price table.
The main argument for not having First Following is "legacy" and "it-will-not-work". But I promise that you will get about the same (but more fair) price curve compared to Price Range.
Is this what you ment?
