I'm reaching out to inquire about your wholesale pricing for your products. We're looking to bulk purchase and would appreciate it if you could share your current pricing, available quantities, and any discounts for larger orders. Additionally, it would be helpful to know about shipping options and lead times. If you have a catalog or any promotional materials available, please include those as well. Thanks, and I'm looking forward to your response!
