I'm currently sourcing 40' x 60' canvas tarps and would like to gather more detailed information on pricing. Could you please provide your best quotes for bulk orders, including any variations in material, weight, or finish that you offer? Additionally, if there are any minimum order quantities or lead times I should be aware of, please let me know. It would also be great to understand the shipping options available and if you can include samples or specifications with your quote. If there are any ongoing promotions or discounts for larger purchases, I'd appreciate that info as well. Looking forward to your prompt response, as I'm eager to move forward with potential orders based on your offerings.
