I'm interested in exploring wholesale pricing for your products. Could you please provide me with your current rates, including any bulk purchase discounts you might offer? It would be helpful to know about minimum order quantities and any available options for different variations of the product. Additionally, if there are any upcoming promotions or terms regarding payment and delivery that I should be aware of, please include that information. I'm looking forward to your response so we can potentially kick off a long-term partnership!
