Wouldn't you like to have pre-orders into your store?
This would make easier for you to manage your storage and depot, saving a lot of money with low-demand trends.
The solution is a web-tool: a Wish list.
Customers can pre-book your products and a threshold is reached, you can re-fill your storage and send an alert to them saying that the products are now in stock.
Just vote and share this idea with all your contacts!
