I'm interested in understanding how your pricing structure adjusts as order quantities increase. Can you provide some details on the pricing tiers or discounts available for bulk purchases? It would be helpful to know if there are specific volume thresholds that trigger price breaks. Additionally, please share any relevant information about lead times and availability for larger orders. Knowing these details will assist me in planning our procurement strategy more effectively and ensuring we can meet our project timelines without any hiccups. Thanks!
