cheapest way to buy quartz countertops?

cheapest way to buy quartz countertops? I am currently working with a kitchen designer (KD) and will be ordering my cabinets soon. However, I'm uncertain if the quoted price for my quartz countertops is competitive. It feels like the KD might be getting a cut when I could save some money by going straight to the source. Does it make sense to purchase them directly from a local company? I don't need to pick out a specific slab; I just want super white quartz. Any advice? Is there something I'm overlooking, like the potential hassle of not having one place handle everything? By the way, I am doing a significant renovation, with my contractor handling the plumbing and electrical work, not the KD place. Thanks!
