farkin lol.
claim some kms.... even 2000 goes unnoticed.
claim under $150 for washing clothes.
stationary, small % of Interne bill for 'research and development' as well as after hours email access, small % of mobile phone bill for work related calls when on the go/after hours.
lots of little things can be claimed, and most are fair to an extent. as long as their some sort of reason begin the amount, you can back-up the claim.
