Yes, you definitely want them to be Good till Cancelled, but so frustrating. This is the last email I have received from them, I have just emailed them again ... they are saying that the duration of the other persons auction is less, but really it's not, I only had a couple of days left and they had five days, though the difference being mine was Good till Cancelled.

Hi buttonsvintageandnewstore,

Thanks for contacting us back.

I have checked the items you've given and the difference I see between these items are their price and their duration. The price of the pink button is lesser. The duration as well is lesser as your item is Good Til Cancelled. However as what James' said, we can't really pinpoint as to what are the factors that make a certain item located higher than you as our Best Match ranking is too complicated.

It filters a lot of factors to arrive an arrange with your search. We suggest you check your items and work on those factors that you can control.

Thank you for choosing eBay.

Warm regards,
