Subject: Order
Dear Mr. Nash,
My name is Paula Washington and I'm the owner of the Four Seasons Greenhouse in Lewis-ton. I was given your email address by Mr. Steve Halloway at the New England Florists' Conven-tion in Boston last fall. I would like to purchase a large number of clay pots from you. Our previ-ous supplier recently went out of business and we urgently need to replenish our stock.
At this time, I would like to order four dozen of your plain six-inch clay pots, for dozen of your plain ten-inch clay pots, and two dozen of your large ornamental pots. I only want to make a small order at this time in order to test the quality of your merchandise. If this selection of prod-ucts from your inventory meets our standards, a second, large order will follow.
Please arrange to have the clay pots delivered to our warehouse as quickly as possible. Be-cause these items are fragile, please forward them by special delivery to ensure that they are not damaged. Also, let me know the name of the carrier you use, so I can access their online freight tracking system while these goods are in transit.
Thank you very much. Please call me at 729-9928 if you have any questions. I hope this is the start of a mutually beneficial business relationship.
Paula Washington
