Purchased an iMAC from this party. Upon set up we realized it was defective.(kept loading on start up but wouldn't ever start.) Contacted vendor and they advised to return it, (We preferred an exchange but they weren't able to provide one.) A few days later the vendor refunds me only $40 of the $450 monitor. They claimed that it was damaged in transit and had to charge me? For a product that didn't work in the first place??? They refused to help. Luckily Amazon took over and solved my issue.This is a shady operation. Stay away. You have been warned. Sent it back with the vendors box padding in a brand new box I purchased.
