One of Elston's rules for chemical inventory management:  If you haven't used it for 3 years, you don't need it. Some exceptions apply, but they are rare.  


There are a few other rules, such as  "expiration dates probably aren't" for most purposes.  I think Ralph hit a good point - you're taking up valuable lab space.

This also plays into the cost of storing chemicals; lab space is much more valuable when it is used to use chemicals than it is to store them. And probably the biggest cost associated with a library of chemicals in storage is paying for the human resources of a librarian to keep track of what is available in storage and what needs to be restocked...
