A common solution to this problem is to make the decision based on the cost of replacing the items. If you haven't used an item in 3 months and it takes 20 minutes and $20 to replace then that's a candidate for throwing out. If if takes 3 days and $300 to replace with little resale value then that's a candidate for storing.
