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.

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