K.i.s.s system

K.I.S.S- keep it simple stupid

It’s a selling tactic when the seller gives the most simple information about the product so it will be easier for you to buy

K.I.S.S system in action-
Buyer: hey, can you tell me something about this dress ..?
Seller: it’s beautiful..(that’s all you need to know)
