Node with many product prices
You should use entity references for this. The end result will be that when you view a parent node, the products show up in a block (or panel pane).


Set up a parent node content type and add an entity reference field to the products content type. 
When you create products, reference the parent node.
Create a block view and add a contextual filter for content: referenced (or maybe referencing). your entity reference field. ?
In that contextual filter's settings, click provide default: content id from url ?
Add fields for the products content type and maybe additional filters as needed.


When you place the block in a region, the products will show up if they reference that node.
