This item when packaged weighs over 500gms and must be sent as a large parcel.  Australia Post has a scale of charges depending on which state you are in.  There is a flat fee for intrastate locations and for interstate locations plus a distance charge.  You will only be charged the actual Australia Post charge plus $1.00 for the bubble wrap.  However, in some interstate cases I can use a 3kg satchel if it works out to be a cheaper option.  There are no handling charges nor any additional amounts for any other materials that I may use, such as sticky tape, printer paper, printer ink, etc.  If you would like your item sent by registered mail, please advise me.  I will combine postage whenever possible.
