I hope this message finds you well. I'm reaching out to inquire about the pricing for your aluminum window corner crimpers. Specifically, I'm interested in understanding the range of options available, including any features or specifications that may affect the cost. Additionally, I'd like to know about bulk purchasing options and any potential discounts for larger orders. Could you also provide details on the lead times for delivery and whether you offer any warranties or after-sales support? This information would be really helpful for me to make an informed purchasing decision. Looking forward to your prompt response so I can proceed accordingly. Thanks!
