A 'Remind me if item is in stock' option
 

Is there a mod for this function?

If an item is out of stock - the user can check a box that will send an email to the user once the stock item is not 0.

Thanks,

We use this.

There is at least one problem I can remember and that is the "subscriber" only gets notified it the inventory update is done via the admin form.

If you are uploading items via CSV then the subscriber is not notified. We had to get this part working. We spoke to the developer and he was not interested in fixing this. He said it wasn't a bug!!.

I seem to remember that there was another problem as well but can't remember what it was.

How well does it work though when dealing with variants ???

I.e if i ran out fo something in colour: red , size: large and wanted to give the customer an option of being told when thats back in stock.

Or does it just work on the product as a whole?

Don't know. We don't use varients. Contact http://bcsengineering.com directly.

As a whole. See it in action on my website.

For products without variants (http://www.fungift.ro/product.php?productid=16232&cat=0&page=1) works perfect.
Even that, i recommend you this mod...it helps a lot.
