nopcommerce 1.90 Customization.
Would like to add the functionality to nopCommerce to be able to supply a markup value to categories or products.
In the store front, the sales price should reflect the cost price + [markup value].
Add markup value to category/categories and all relevant product sales prices in that category should get calculated accordingly. (Cost price + [MarkupValue] = Sales price)
Administrative section should be added to modify the markup stuctures. Add/Edit/Delete the markup values per global category, sub category or even at product level.
If product level markup value exists (not null) then the product markup value should be used, not the category markup value, to calculate the sales price / visible price in the storefront (customers can see).
