Hello everybody,

I am glad if anybody can share some web sites to learn or his personal expertise.

Specifically inquisitive about:

* How do they set a value to remain aggressive and nonetheless be worthwhile?

Talking different phrases, I might wish to understand how large e-commerce firms work with information — the place do they take the info for evaluation and which of analytics/scraping instruments are they utilizing.
