How to handle a part that we get from multiple sources

How to handle a part that we get from multiple sources

Hello,

If i have a part that I can get from different vendors depending on who has it in stock, is there anything i need to do differently when putting it into inventory?

For example:
If we are installing an septic tee, we need an Infiltrator Septic Tee.  I can buy them from Bob's Septic Supply for $25 or I can buy them from Joe's Septic Supply for $35.

Obviously I'm usually going to get them from Bob, but if bob is sold out I have to buy them from joe.
Do I just put the higher price in when i make the item or what?
