We cannot do this. Postal regulations require that we post the actual retail amount of a commercial product in the package. It is illegal to do otherwise. Any requests to adjust customs fees will be ignored; please do not ask. We also cannot mark your shipment as "gift" to avoid customs fees. You are responsible for these taxes; we have no control over import taxes that are added by customs in your country. If you plan to purchase frequently within the US, you may want to consider Viabox.
If you shop online stores in the USA quite often, you may also find that Viabox may provide a solution for cheaper shipping rates. You can have multiple orders shipped to a Viabox supplied USA address, enjoy the low or free shipping rates from various domestic retailers, and pay a lower fee to Viabox to have the combined order shipment delivered to you.
