Hi,
Development of version2 is all but stopped apart from bug fixes and sponsored work. All effort is now directed to version3.
However in NB_Store you already have Normal price, dealer price and discounts that can be applied to these. Discounts can also apply to specific roles, so you can give different dealers the price you want by placing the product into different discount categories. You can all create bespoke fields to display any other prices like your MSRP field, although there is a wholesale "Cost" price included in the model record. To be honest I can;t remember if there is a TAG for this to use in the templates, but I think you can display this using the model table display...you'll need to play around a little with it.
Your problme is here that discounts are all category or cart based, not producted based, so you'll need to group or even have a category per product.....obviously not good!
In version 3 we will review this, but the first task of version3 is to get something working for the normal day to day store. Your need sound a little more advanced and would probably need a bespoke price provider plugin. The "Plugin/Event trigger" concept is something that is going to feature highly in version3.
Regards,
Dave.
