Unfortunately we have had to implement a minimum order due to the costs of processing payments packing and so on.
We have a minimum order amount in the online store of $20 excluding postage.
This helps ensure we’re not packing a $1 item and charging $10 in postage.
In most cases its better value for the customer to order $20 or more when having items shipped. If the item costs less than postage then it can make one item very costly.
