That assessment highly depends on your region I assume. They are far from 7 day shipping for me. In fact, it's the same 2-3 days as Amazon for non-Prime customers here. Speaking of non-Prime, free shipping is also at 50€.

The limited selection is certainly true but mainly it misses drop shipping stuff and what's essentially a mirror of aliexpress with a huge markup. I don't really miss those. In fact, it requires a considerable amount of time to navigate through those offers on Amazon, so not having them is a plus in my book.
