I like to schedule lots of my listings and I have found that it only see,s to be free if it is to start within 24 hours

i'm very confused with it though

I have been selling off some of my day's old stuff and I like them to end on a Sunday so I was going to start doing the listings up today and schedule them but then it seems I will have to away that 40 cents so I will attempt to so them all tomorrow night

If someone can tell me what I am doing wrong it would be awesome
