I want to add some prefix to order number.
Our website has 6 stores and i wanna classify which store customer purchase the item.
You know, orders in ebay and amazon already have their own prefix to order number like this
But orders proceeded in our own website do not have the prefix, just store_id + number
How can i add some text prefix to order number? I think by using store_id, i can add them but i don't know how to do. Thank you.
