Please, rather than C&P the same reponse each time, can you feed back to the relevant team that the 'dynamic calculation' does not work.

I have a 4 day despatch time set because there are issues that may cause me to take this time to post. However, because I usually, manage to send same/next day, ebay decide to override my 4 day time. If anything happens that my OH is unable to drive, or the car is out of action (both of them are getting older and less reliable) I will need those extra days, as, if I have to rely on friends/family, I will only ask them to go to the delivery office no more than twice a week.

Why ask us to set a despatch time, only to override it?

Can we look forward to 'dynamic pricing', where ebay decide the item cost for us anytime soon?
