For people which don t have a lot of money, it is usually the best way to avoid resellers and buy directly from the manufacturer. Many of those who are interested in selling products, they often sell their products also on ebay and on Aliexpress.
Ebay has the Ebay Global Shipping program. This is most often the most cost-effective way to buy products from US in Switzerland. With Ebay Global Shipping program, shipping time is short, shipping costs are optimized and import taxes are included. In Switzerland, it is often not worth to buy from sellers who do not offer their products on Ebay.
The same with Aliexpress. Aliexpress offers the Aliexpress standard shipping. In Switzerland, Aliexpress standard shipping is attractive. DHL or other specialized transport companies have higher prizes.
Companies which do not sell their products on Ebay and Aliexpress often seem not to be interested in selling products on the most cost-effective ways to foreign countries.
Greentek Sensors seems to be one of those. William Croft from OpenBCI once recommended to build EEG caps ourselves. This is eventually better than buying them from sellers which have offers which are not competitive.
We made some suggestions how to improve for instance Gel-free EEG caps. These instructions can be found in our journal.
