Hi Jim

Thank you for reaching out to At Large Audio and showing interest in our 4 x Speaker Suitcases. Below is a button that will lead you to a PayPal page, in which you can purchase the 4 case. 

As mentioned in my email, we are happy to also provide 1 solar panel for free that will charge these solar panels. This is valued at $149 but is yours for free as you are purchasing 4 speaker suitcases in total. 

If you have any questions please email or call at anytime.
