Dear Department/Company:
I hope this letter finds you well.
As you may know, I am currently in the market for a sample of product. After researching and comparison shopping, I believe that your product is best suited to my needs.
I would be interested in receiving the following sample product: _____________.
If the product meets or exceeds my expectations and I decide to order in bulk, I’ll be sure to get back to you and discuss further details.
I would appreciate it if, in exchange for the sample product, I could provide some form of remuneration. Please let me know what type of payment would be acceptable to you.
If you are not comfortable with a negotiated payment arrangement, then I am more than happy to pay a flat fee for the sample.
If you require any further information from me, please do not hesitate to contact me.
I look forward to hearing from you.
Sincerely,
[Your Name]
