Primarily because NGS does not ship outside of the USA! Thinking about the many costs of international shipping, theres the actual fees, and time standing in line at the post office, only to fill out governmental forms that they will then inspect and scrutinize. On top of the time and effort required, next up is customs, who seem to rip open packages indiscriminantly. and long distance shipping, too easy for your package to get lost. Due to the diverse issues and additional scrutiny, it's much safer for both parties to simply declare a 'NoGo' attitude, and shop locally. Better for your economy anyhow. Bottom line is that international shipping is simply in neither your, nor our, best interest. SO - ALL THAT BEING SAID; instead of teasing you, wasting your time and our bandwidth, we implemented a strategy that blocks NON-US visitors on 4/25/2022. If you are an international visitor and can view/read this, the site is be temporarily allowing NON-US visitors for site upgrade testing purposes. This temporary access is for a very limited time.
