My goal is to create a notification when a product is about to expire.

You will need to provide more information - what are you stuck with ?

If I understand you correctly you want to store all the product information in a DB including expiry date.

Then you just need to select the data say once a day from the DB and compare it to the date now and if it is less say than one week you need to flag it.
