The US shipping cost is what they show, but I imagine they just charge extra shipping for non-US residents. Have you tried to buy anything and been refused?
Here's what their FAQ page says about international shipping...
Do you ship internationally?
We do everything we can to ship to as many countries as possible, but unfortunately we cannot always include every country for every drop. Some countries cannot be included due to logistical difficulties. On other drops, we cannot include international shipping due to vendor limitations. Lastly, certain countries have more restrictions on certain types of products, such as knives, vaporizers, flashlights, Kinder Eggs, etc.
Could there be additional fees for international orders?
For all countries, the taxes levied on imported goods is up to the discretion of the customs agent in the country of importation. Every country is different, and we simply can't keep track of each country's varying import costs for different products. It is the responsibility of the importer (international customer) to be aware of the relevant laws and taxes that their country imposes on them.
How do you ship internationally?
Most international packages are shipped via UPS Mail Innovations, a service where the parcel is picked up by UPS, passed on to USPS, taken to another country, and finally handed off to the local postal carrier. This method of shipping is actually cheaper than USPS by about 30%, and we pass those savings on to you. Some international packages may be shipped via DHL or USPS.
How long does it take to ship internationally?
These are the rough estimates for different countries based on our experience. Please keep in mind that shipping times can be shorter or longer depending on shipping or customs delays.
Canada: 1-3 weeks from the shipping date
Australia, New Zealand, Germany, France, and UK: 2-4 weeks from the shipping date
Countries not listed: 3-6 weeks from shipping date
