You have the option to enable/disable the gift-wrap option for your customer from the 'Checkout options" section of your store dashboard. Of course, it is entirely up to you as the store owner, whether you want to charge additionally for that, or offer it at no cost. In case you want to charge extra, we have also included the option for you to specify the additional charges on the same page.

Go to settings>>click  on checkout options>>Select allow gift wrap option>>turn on the option for gift wrap>>click on save.
