I'm currently exploring options for sourcing products and would appreciate it if you could share your latest product catalog along with the corresponding pricing details. It would be really helpful to have a comprehensive overview of your offerings so I can evaluate which items might align with our needs. Additionally, if you have any special promotions or bulk order discounts that could apply, please include that info as well. Understanding your pricing structure will allow us to plan more effectively. Look forward to seeing what you have to offer!
