Subject: Agreement on Product Pricing and Invoice for Free Sample Request Dear Mohammad, I hope this email finds you well. We are delighted to hear that we have reached an agreement on the pricing for our products, as well as the first order and annual task. We are looking forward to working with you and your team. Regarding your request for a free sample, we apologize that we do not have a precedent for providing free samples as our products are of high value. However, we have prepared a formal invoice with a 25% discount for you. Please find the attached sample. To facilitate payment and expedite the shipment of the sample, we kindly request that you use either Western Union or PayPal as your payment method. We believe that this will be the most efficient way to process the payment and ensure timely delivery of the sample. We look forward to receiving your payment soon and hope to continue our collaboration in the future. If you have any questions or concerns, please do not hesitate to contact us. Best regards, [Your Name]
