Mr. Boss POS System

I ordered this and it was delayed in shipping, so I no longer need it. I am unable to return it so I am selling it. I opened the box just to show pictures of actual product. I bought it because it said it could be used offline and I mainly wanted it for cash sales. It includes the pos software to be downloaded. I have never used it, never installed software etc. I paid 469 plus shipping and sales tax. I am listing it for 400. Free shipping in the USA.
