In Zik, what does the "C" stand for? What should we do with it? Why don't I see the C that Nahar has in his training video?
The C means competitors. This field is only visible to those who have the browser extension downloaded.
As a general rule, Nahar recommends not selling an item with 10 or more competitors unless we can sell it for a significantly lower price than any other seller.
