Dear sir or madam, I am so appreciated that your company can give me this opportunity to have a position. However, after my careful delibration, I think I can't accept your kindness. The most important cause is the post you give me is not really fits me which I fear I can't be qualified for it. I prefer to do the computer design which is accordance with my major. Second, I am required to have many long business visits in another cities or countries by your company. In fact, I have told in my application that I don't accept any business travel even several days. Finally, the salary you supply is too low for my prior expetation. At least, it should afford my living, but it can't. Hope you can accept my apology and find another one to this position soon.
