I'm reaching out to request pricing and additional details for the items classified as TBA in your catalog. It would be great if you could provide information on the available options, including specifications, minimum order quantities, and any volume discounts that may be applicable. This will help us better understand how we can integrate these items into our upcoming projects. Additionally, I'm interested in lead times and any special terms associated with the TBA items. If there are any samples available or specific certifications related to these products, please include that info as well. Looking forward to your prompt response, as we're keen to move forward with our procurement process soon!
