Super quick, super cheap, super easy
Why bother going to the post office with long queues and inflated charges for parcels? You can even post via parcelforce using interparcel for a FRACTION of the post office price. I have used interparcel twice now and have nothing but praise. Printing the labels is quick easy and then just wait for the courier to come to you! If you are able to be around to wait for a courier, either at work or home, this is the service you should be using!
