Usually they have a promotion method, that is to say, some company departments engage in group buying, and they add you to the group buying list, so that the price can be lower, but the quota is limited. Sure, it's just that I want you to get a card. So, you can ask him directly if there is any company group purchase. To do this, first, you can let the sales staff know that you are not a water fish, but only know a little. Second, let him have a step to reduce your price, hehe.
