Is there a bundle or package app that makes a fixed bundle? by Renee

Hi, I'm looking for a bundle or package app that creates a fixed bundle (3 items all with their own SKU) but must be purchased together. In other words you can only buy the bundle (which consists of the 3 items). Ideally, it would show the individual prices that make up the bundle. The customer will be billed for all 3 and can't remove anything. 

I've looked, but can't see one that seems to do that.

Thanks
