I'm looking to source information regarding concrete bits suitable for the US market, specifically their sizing options and pricing. It's important that these products can be shipped to Canada, so I'd appreciate it if you could provide details on your inventory. Additionally, please include any minimum order quantities or bulk discount options available. I'm keen to understand the lead times for shipping as well. Your prompt response will help facilitate this procurement process smoothly. Thanks!
