I'm reaching out to inquire about the wholesale pricing options you offer for your products. I'm particularly interested in understanding the different tiers of pricing based on volume and any potential discounts available for larger orders. Additionally, could you provide details on the minimum order quantities and shipping costs associated with these wholesale prices? It would also be helpful to know the lead times for production and delivery, as well as any flexibility you might have regarding customization options. I'm looking to establish a long-term relationship, so details on your payment terms and return policy would also be appreciated. Looking forward to your prompt response with this information!
