Dear Mr. King,

Your supermarket chain is excellent in many ways. I enjoy the things you sell, such as the selection of produce (农产品) and fresh bakery items. I have been a long time supermarket shopper and hope to continue for many years. I have found, however, that I must make a separate shopping trip to one of your competitors because there are many items your store does not carry. This becomes inconvenient for me, as my time is valuable, and I do not like to make two trips. Your low prices and excellent customer service keep me coming back to your supermarket, but I would be a more satisfied customer if I could find all the items I need in one place.

To tell the truth, I have never been able to purchase nacho (烤干酪辣味玉米片) cheese soup at your store. I can find other flavors (味道) of soup, but your store does not carry nacho cheese soup, a common ingredient (原料) in many of my recipes. In addition, I can only find large wonton wrappers (馄饨皮), while many other stores carry both large and small and offer a more varied selection for their customers. Another example is Regent Brand Chili Seasoning. Though it is not a leading brand, it is still common on the shelves of other grocery stores in this area and is superior in flavor to its competitors.

I sincerely hope to continue a relationship with your store, and I hope that you will consider the possibility of expanding your goods to be more competitive.

Yours truly,

Bob Watson
