[Amaaazing]

I'm new to ebaying and want to sell an item as "buy it now" for £10 but it seems I have to enter an auction starting price too so what do I write? It didn't seem to allow me to set a reserve price, so am not sure what I am doing wrong.

You need to change to the advanced selling form. On your selling listing page, at the top right there's a line that says switch to a form with more choices.. click that then click continue. Then when you get down to the bit where you put your auction price in, click the 2nd tab which is fixed price. This is your buy it now.
