Re: Product expiration date
Its more complicated than that, because isn't it possible you can have multiple expiration dates for the same product? You get a new batch in, while the older batch is still sitting on the shelves?
Also, you need to tie the quantity purchased to the dates - because 12 will have an expiry of 12 dec and 12 will have an expiry of 18 dec, so as you sell out the first 12, the expiration date on the website needs to update.
And, the system needs to know how much to turn off, when you reach that expiration date. If there are only 3 left on the shelves that are a week old, it needs to remove those three from the quantity, rather than all of them.
Sorry, I can't be of more help, but it seemed like the solution you guys were discussing probably doesn't fully fulfill your needs.
