The true cost of the wrong postage
Sadly we have had quite a few of these recently. If you are unsure of the correct postage, always take your parcel to the post office to check the postage.
A good principle to use is that if your parcel is thicker than a DVD case it would be classed as a small parcel which costs just £3 to send second class.
Any surcharges we incur from Royal Mail are deducted from the donation to your chosen charity or fundraiser so it really important that the correct postage is paid.
