Hi. I use the Royal Mail SmartStamp service and it has saved me lots of time and hassle posting items to buyers.
FYI SmartStamp is a service from the Royal Mail that lets you print the postage you need 24/7. It doesn't matter if you are sending a big parcel or a small letter.
You can find details on the Royal Mail website at http://www.royalmail.com/portal/rm/j...mediaId=600023
Happy eBidding!
