Here are some of my favorites out of the bunch...
Supply Tins. We all keep mints in our purses or pockets for first kisses or important work interviews. Once you've run out, don't just toss that little metal tin. Use it to store bobby pins, paper clips, thumb tacks, etc. Look how cute this would be sitting on your desk or in your bathroom.
2. Use glue to affix the cover to the tin.
3. Label the top to indicate what's inside.
Cost: less than $10
