In addition, you might pay more for shipping if you purchase parts from multiple vendors, as compared
to the shipping and handling charge when you purchase a complete system. The cost rises
further if you encounter problems with any of the components and have to make additional calls
or pay for shipping charges to send improper or malfunctioning parts back for replacement. Also,
many companies charge restocking fees if you purchase something and then determine you don’t
need it or can’t use it.
