23rd November, 2007.
We take this opportunity to extend an invitation to you for the sale of our latest products in the unique “Super Sale”. As a valuable customer of our products in the past, we extend this special invitation to you. This would let you enjoy a special discount of 20% on purchase of products worth $100 or more.
The Exhibition Sale is on Invitation only, so we would request you to kindly bring this letter along to avoid any inconvenience at the venue. We would also like to let you know that the products on sale are one of a kind and absolutely the latest in the market.
We look forward to your continued support for our products.
