I'm looking to get pricing information for wire line cables, specifically the ones with 7 connectors and mono connectors. It's important for us to understand the pricing structure, including any bulk order discounts or variations in pricing based on different order quantities. Additionally, could you please provide details about the lead times for delivery and any available certifications for quality? This information is crucial for our procurement process and will help us make a more informed decision. Thank you!
