Add-on Eligible for Free Shipping When Buy Together with Keyboard

We will offer free shipping only for the add-on/s below when you order them together with our keyboards and (or) mouse.

The reason is that we don't make enough profit to cover the shipping fee for our keyboard products and mouse, but our shipping company offers us a discount when we ship the add-ons (not including the Carrying Case) together with keyboards and (or) mice, and we pass along this discount to our customers.
