I to this day have proudly never bought anything from Amazon (unless you count the one ebay purchase that was shipped from Amazon without my knowledge). However I have run into a couple of products, namely quality name brand USB4 cables (Plugable and Ugreen) that I for the life of me cannot find anywhere but Amazon in Australia.
So yes I have proudly survived without Amazon until very soon. I will try to continue to not use Amazon however with some sellers opting to exclusively sell on Amazon, I feel I am being left with no choice. It seems not enough boycotted Amazon when it mattered to the point that there are an increasing amount of items that are only available through them.
Facebook and Amazon are on my shit list due to their shear contempt for their customers/products and employees.
