When you are in the order cart, click on the “Remember cart” button, then indicate a label to create a draft order:

In the “My Orders” menu, if you have saved draft orders, the “Basket Drafts” submenu is accessible. Click on it to access your various drafts.

You can then delete a draft using the button or use it using the button .
Your shopping cart is then recreated (products and order settings) using the draft. However, you may need to recheck certain data if there have been changes to settings in the meantime (stock, quotas, product availability, etc.).
