All our parcels are sorted by weight sometimes this causes an undercharge on postage…..an example is a bobbin winder is very light but to big for an envelope, same applies for Kreinik, this is in new packaging unfortunately and no longer will go in an envelope, it must go tracked parcel rate.
If this happens we will send through an invoice if required at time of departure for the package, it doesn’t happen very often, if you do not wish to pay the extra postage we are more than happy to refund the parcel for you.
This was deemed the fairest way so as people do not get overcharged.
From September 1st parcels requiring extra postage will not be sent until this has been paid.
