5. What should I do if the products is sold out?
When a product is temporarily out of stock, you will still be bale to view it on the website, but you cannot order it.
In order to receive a notification email when the product is put back on sale it is very simple: Either you are logged into your customer account, and you just have to go to the product page and click on "notify me when the product is available".
Either you are not connected, or not yet customers, and you have to go to the product page, and replace "firstname.lastname@example.org" with yours, then click on "notify me when the product is available".
