Hi

Due to Postal strikes I have enlisted a courier and it seems to be working. But my customers until now have been able to choose from 3 delivery options.

I would like to change the shipping to a single flat rate with free shipping over a certain amount.

To do this I would need to know when they require their order as 90% of what I sell is custom made.

Does anyone know if and how I could do this?

Thank you.
