What is kit in sales?

Excuse me, could you please clarify what you mean by "kit in sales"? It's not a commonly used term in the world of finance or cryptocurrency that I'm familiar with. Are you referring to a specific bundle of products or services that are marketed together as a single offering? Or is it a particular strategy or technique used in sales? If you could provide some more context or an example, that would be very helpful in giving you an accurate answer.
