Request for Purchase of Sample B

Dear [客户A],

I hope this email finds you well. I wanted to follow up on our recent meeting and the discussion we had about providing you with a sample of product B for research purposes.

After further internal discussions, our company has decided that we would prefer to offer product B for purchase, rather than as a complimentary gift. We believe that this approach would be more appropriate and fair for all parties involved.

I understand that this may be a change from our original agreement, and I apologize for any inconvenience this may cause. However, I want to assure you that we remain committed to providing you with the best possible products and services.

Please let me know if you have any questions or concerns regarding this matter. We value our relationship with you and look forward to continuing to work together in the future.

Best regards,

[Your name]
