"Bigvalueinc sold me a used Canon 5D III then replaced it with another use camera, never denying the fact the 1st. one was used. They then blocked my account from making additional purchases and literally told me if I would revise my negative review they would exchange my camera! When that didn't happen they appear to be refusing to ship a replacement camera and just mentioned Refund in an email. SHIFTY, UNTRUSTWORTHY AND INCREDIBLY UNPROFESSIONAL....DON'T BE LURED IN BY THE PRICES! BUYER BEWARE...YOU'VE BEEN WARNED!"
