Calculating postage costs can be a time comsuming matter especially when you have 10 parcels warpped up but not stamped. Imagine going to the post office and the time wasted weighing each one on their scales.  Also holding up other people in the queue which can be a frustrating experience for you and others.

To rectify this matter-all you need is some electronic scales and the royalmail site. Go to google and type in royal mail there you will see the royal mail site   It has all the information you need for packet sizes and a variety of postal services and postage costs,saving you time and money in the post office. 

More than likely many ebayers will know about this site but thought Id mention it for the ones who dont. 

Happy packing!
