I'm looking to source some wholesale herbal oils and would appreciate your pricing details for a 5L bulk order. Specifically, I'm interested in rosemary oil along with a mix of other oils, including jojoba, vitamin E, hemp seed, argan, and avocado. Could you provide me with your best pricing options, including any discounts for larger quantities? Additionally, please let me know about the shipping options, lead time, and any available certifications for these products. Looking forward to your prompt response!
