I'm interested in exploring your product range and would appreciate it if you could provide me with your wholesale price list. It would be helpful to have a clearer idea of pricing structures and available options. Additionally, I'd like to request some samples so that I can assess the quality firsthand. This would greatly assist in my decision-making process and potentially lead to a larger order in the future. Looking forward to your prompt response!
