It can be both. Traditionally is was a ‘war dance’, but depending on the lyrics and context it can be used as welcoming, a farewell, or many such things. You would have to translate it to know.

Given how terrible the amazon search functionality is, I don’t see how this would work. There is an overwhelming number of products available there, so it is easy to find what you’re after eventually, but in my experience, the only way to actually find a specific product is with an external search engine.

My normal search pattern goes something like: pricespy/digikey/RS/mouser > if not available, or too expensive> aliexpress > if too much to sift through > google shopping > (this is where amazon links live)
