Hello,
My client has an apparel shop, and on every order she adds a free cotton bag to the customer.
Because some of the customers are repeating customers, they started to complain that they get too many bags 
She wants to add the option on the cart to select whether or not to receive the free bag.
So it can be done by adding a check box to the cart or something similar, then this data needs to be saved in the order.
I saw the guide how to do it in the normal cart, but I was not able to do it in an ajax/drawer cart.
Can someone please suggest how to do it, or any other idea to allow the customer whether or not to receive a free bag?
Thank you!
