this is what the Australian consumer comission states but i doubt it has any reasonable grounds in this case as glowforge in based in the USA.
Returning the product
You are entitled to return a product if you believe that there is a problem. You are generally responsible for returning the product if it can be posted or easily returned. You are entitled to recover reasonable postage or transportation costs from the business if the product is confirmed to have a problem, so keep your receipts.
When a product is too large, too heavy or too difficult to remove, the business is responsible for paying the shipping costs or collecting the product within a reasonable time of being notified of the problem.
the only other option i see is to contact the Bureau of Consumer Protection to find out what local laws there are in place in relation to this kind of matter.
