I hope you're doing well. I'm reaching out to gather more details regarding the products we discussed earlier. Specifically, I would appreciate it if you could provide me with your pricing options and current availability. Additionally, if there are any bulk purchase discounts or lead times I should be aware of, that information would be incredibly helpful. Looking forward to your prompt response so we can move forward with our plans. Thank you!
