Change from online auction to Buy It Now????

[kates-apparel]

I accidentally made a couple of my listings online auctions when I wanted them to be Buy It Now how do I go about changing them without ending the original listing?

You can't.  You can add a BIN to an auction style listing but that disappears when a bid is placed.

If you want a BIN only, you need to end the listing and relist using the fixed price format.
