Can we add "wait list" option?
Is it possible for us to add a feature to our site that will allow people to enter their email if they'd like to be notified when an item or size is restocked?
Something like this is already implemented on your new website. For example, you can see this feature by going to the following URL (I just picked some random old product):
As you can see the visitor is asked to signup for your mailing list. This feature does not automatically notify the person when that individual product comes back in stock. We decided not to implement this feature in this manner because very few of our customers have products that come back in stock like this. Very often the products are here for a month or season and then gone forever.
