This depends if you order from either our UK or US site, and where your order is being sent. Some countries have a customs threshold. If your order value is higher than the threshold in your country, a tax or handling fee will be added. It varies, so please check with your tax and imports office beforehand to see if it affects you.
If you are affected, your order may end up costing around 20% more. It depends on the size of your order, but the extra fees can be upwards of €30.
