How the hell does anyone buy from amazon?

I am in australia if that changes anything, but i really can't understand how amazon ever became a massive "marketplace" for e-commerce because every single time i have tried to check prices, or search for something it shows horribly useless results.

From products that are not related, to just showing products that are not what i searched.

Example, i was just trying to find a replacement eaton EBM cable. It is maybe 12-16 inches long, has some plastic clips are either end, and can carry 30amps at 36volts DC.

Should be less than $25 usd - with free shipping probably.

The website and the app will show me a list of UPS's and will show me eaton brand products but will not filter them, or even sort them low to high.

Honestly, this is extremely ineffective search, bad prices and frankly - the most convoluted storefront process e.g. usa is different to australia and have different logins.

Does anyone think buying things on amazon is easy?
