General Warranty & Returns Policy on PC Used Items & Repairs

My warranty policy is as follows:  computer, monitor,   printer returns: three (3) days.  Software, carry bags,   surge suppressors, cables, or any and all other items:    no returns are allowed.  Computer repair is 30 days      for labor and 30 days for parts.  Monitor and printer   repairs are not supported.  If an outside warranty   exists on anything, I do not warrant it and there may   charges for any related service calls or consulting.    The purchaser or client may call anytime for support   within the initial warranty period.  After this period, I    may take nominal, short support calls within reason.    If the person does anything that undoes, undermines,   or negates the work I have done, and causes me extra   time to fix any or all associated problems, then my   warranty is automatically voided and must be re-   negotiated.  If the client changes any software, hard-   ware, or firmware settings, there may be additional   charges for any or all time spent on any needed fixes   or modifications relating thereto.  A small amount of   training or instruction time may come with the equip-   ment sale but this warranty does not imply any extra   training or instruction time.  I reserve the right to   cancel or modify any sale, work, invoices, fees, billing,   or warranty terms before they are executed.    No exceptions.
