VOLARE GIFT SHOP343 Hedge Street, Hickory Hills, IL 60457 www.volaregifts.comMarch 28Francesca Balaguer 3376 Bruce Avenue Maryland Heights, MO 63141Dear Ms. Balaguer,It was great meeting you at the trade fair in Belgrade last week. As we discussed, I’m interested in purchasing some of your souvenir products for my gift shop in Rockford, Illinois.We haven’t been very pleased lately with the quality of the merchandise from our current supplier. In fact, many of our customers have complained about the substandard items. I think that this is one of the reasons why our sales have recently declined.Viewing your exhibit at the trade fair, I was impressed not only with the superiority of the materials that you use, but also with the intricate detail in each of the designs.Enclosed with this letter is an order form that I downloaded from your Web site. Please let me know if you can produce the requested items for us. We are thinking of introducing your merchandise in time for the summer tourist season, when we get twice as many visitors to our location. If successful, we would be interested in developing a long-term business relationship with you.If you have any questions, do not hesitate to send me an e-mail at octavio.guzman® volaregifts.com. Thank you and we look forward to hearing from you soon.Sincerely yours,Octavio Guzman Co-owner Volare Gift Shop  To: Octavio Guzman <octavio.guzman@volaregifts.com>From: Francesca Balaguer <f.balaguer@terrestrialcrafts.com>Date: April 15Subject: OrderAttachment(s): Sales invoice, Contract Dear Mr. Guzman,I appreciate your interest in Terrestrial Crafts. I'm very grateful for your order considering that I started this | business just a few months ago. My exhibit at the trade fair was a success, and I received proposals from several companies during the event.Since you ordered more than 50 different types of items from the catalog, it may take me longer than usual to finish making all of the items. However, I’ve recently hired five assistants to help me out with production, so I am confident we can send the items to you at the start of your busy season.Attached is a scanned copy of the signed contract, as well as the invoice for your order. For any inquiries, please give me a call at 555-0099 . You may also check out my Web site for information on new products at www.terrestrialcrafts.com for any future orders. Thank you very much.Yours,Francesca Balaguer
