I'm reaching out to inquire about your wholesale program. I'm particularly interested in understanding the structure of your pricing and any minimum order requirements you might have. It would be really helpful if you could provide an overview of the benefits available for wholesale customers. Additionally, I'd like to know how I can obtain samples of your products. Could you please share the process for requesting samples, including any associated costs or conditions? I'm eager to evaluate your offerings and explore potential collaboration opportunities. Looking forward to your reply!
