Multiple postcode route planning

Hi I am looking for some software or website where I can enter multiple postcodes for it to then put them in order. Any ideas??

Thanks

This might do what you want OptiMap | Route Planner for Google Maps

Dont know if this is any good pal. Saved it to favourites a while back but havent had a closer look yet.
