I hope this message finds you well. I'm reaching out to inquire about the pricing for your products. Specifically, could you provide me with the price per unit? It would also be helpful to know if you offer any flexibility in terms of customization, particularly regarding the melody options. We're interested in unique melodies to better suit our project needs. Additionally, could you please share any details about minimum order quantities or bulk purchase discounts? Understanding these aspects will help us better plan our procurement strategy. If there are any catalogues or product sheets available, I would appreciate it if you could send those along too. Looking forward to your prompt response so we can explore potential collaboration!
