Currently, I use Odoo V8. I need to keep track products expiry in Odoo. Here is my scenario:

I am using Odoo for a Pharmacy's Store. All products definitely have their own Expired Date. So, I need to keep track this Product's Expired Date (i.e: 6 month before Expired Date) and Odoo will send notifications to me about all products which are nearly expired.

This can allow me to Take Out that products from current Inventory Locations and move it to another Locations (lets call it Clearance Locations) for Clearance Sales purpose.

I install module product_expiry, which has fields of Best Before Date,End of Life Date, Removal Date and Alert Date, but  I'm not really sure how this module work. 

Can anyone here help me for this?
