Question

I am trying to tell the difference between trade credit and opportunity costs, but now liking what I find on the internet. Is there a link that shows both? I could not find one. In order to do my assignment I need to compaire the two so I could figure out how opportunity costs are involved with trade credits. I do find the definitions of each one through the computer and with my reading, but I want just one site that has both in it.

Hope you can help!
