Dear :

We are a large retail chain specializing in business. We have recently received a number of inquiries from our customers in [area/country] for your [product]. We have also learned from other sources that there are good prospects for the sale of this product. We would like to suggest that you send us a trial delivery for sale on consignment terms.

We make this proposal, hoping that we will place firm orders when we feel sure that the market is established. If you agree, we will get down to details in regard to payment, commission, and so on. You may check our standing with [bank], our banker.

We look forward to your early reply.

Sincerely yours,
