I'm interested in purchasing a roll of solar wire that's specifically 8 AWG, in both black and red colors. Can you provide me with a price quote for this product? Additionally, I would appreciate it if you could include information on any bulk purchasing options or discounts you might offer. Furthermore, please let me know about the availability of the product and the estimated shipping time to my location. Any details regarding the quality standards or certifications of the wire would also be helpful. Looking forward to your prompt response.
