I understand your concern. To maximize possible deductions, you might want to explore the "expenses incurred in a trade or business" rule. For detailed information, please follow the link to "small business expense reporting". Also, carefully reading the instructions accompanying the form will give you a clearer understanding of what can be claimed.
That all depends on your total taxable income, and where you work.
