The best way to get around this is to do a scheduled listing. Do your listing as normal and instead of listing immediately click on the scheduled listing box. You will then be prompted to enter a time and date for the listing to start. This action would normally cost you 6p in fees but if you then go back into your scheduled list before the time and date that you have set and tick list immediately then the 6p is not charged. You can do this for about 3 weeks in advance. So for example if I do a scheduled listing today for 3 weeks time but I really want to list it in 2 weeks time, on the day I want the listing to start I just go into my scheduled list and tick list immediately and no fees are incurred.
This might seem a bit long winded but I use this method all the time and it works.
