I'm looking to get detailed pricing information for your products, specifically the total cost per unit and any bulk purchase discounts you might offer. Additionally, I'd like to know about the various shipping options to Spain, including estimated shipping costs and delivery times for different quantities. It would be great to understand if there are any specific shipping requirements or preferences you might have. Also, if there are any associated fees, like customs or handling charges, please include those in your response. I want to make sure I have a clear picture of the overall expenses involved. Any information regarding lead times for production and shipment would also be appreciated so I can plan accordingly. Looking forward to your prompt reply with all the details!
