If your order shipped via a method shown as "Fully Insured" and suffered non-cosmetic damage, just write to us via our contact page and let us know your situation and we'll be happy to help.
Otherwise, if you did not have a "Fully Insured" shipping method, your only recourse will be with the shipping company through which you may be able to file a claim depending on the shipping method you chose.
Fortunately, damage during transit is very rare.
