I've a feeling I'll give them a try.
As a sideline I sell antique books and last Monday morning saw me staggering to the post office with 7 packages. They were quite big and heavy so it took two journeys from the car to the post office, thus having to join the patiently waiting queue twice.
Looks as if this company will charge roughly the same with the added advantage I dont have to leave the house. Thanks for the link :-)
