According to our records, in the past twelve months you have purchased over $[XXX] in merchandise from us. This pleases us greatly. However, since you have never taken advantage of our 2% discount for early payment, we thought you might be interested in how substantial your savings could be. Your savings on last year's purchases alone would have amounted to $[XXX]. Over the period of a year, by paying us within 10 days of delivery, you can actually save in one year 24% of the face amount of an average monthly. In fact, some firms prefer to borrow funds to take advantage of this discount. Of course, you know what is best for your business, but we just want to be sure that you are aware of this potential savings. We would like to take this opportunity to thank you for the orders and the promptness with which you have always paid. It is a pleasure doing business with your firm.
