You can find our products sold in malls and supermarkets in Belgium, France, the UK, and the Netherlands.We are pleased to say that this year we are expanding our operations into the Asian market, starting in Japan and South Korea. However, we are concerned that our current supplier, Ganesvoort Distributors, does not offer a wide enough variety of items. That was why we were pleased to find out that your company has such a huge selection. We also know that you offer a special promotion to new clients. While Zoet Bonbon only requires 9 tons of products for this year, we are hoping that you will provide us with a 20 percent discount if we sign a five-year contract. Let me know if this is possible.I would appreciate it very much if you could provide us with more information about your services. Please contact me directly at (+32) 555-8169 as soon as possible. Thank you.Liesbeth Weidman
