How do you move a "buy it now item" over to Auction?

[ragsdownunder]

I have a listing with a "Buy it now" price, a lot of watches but know buyers. To the right of the listing it says "Move to Auction". Can anyone tell me how to do this, it all seems very confusing.

You still have over 2 days to run on your current Buy Now so if you have a lot of watchers why not revise the listing to add Best Offer? You may get an offer that you're happy to accept from one of your current watchers.

If you click the Send to Auction button you effectively end your Buy Now listing and start a new listing as an Auction with the option of also having a Buy Now price. If you have both options the Buy Now price must be at least 30% more than your Auction price.
