I encountered the same with the c9 model.
They claim the cheaper unit is non-OEM and gauranteed to meet minimum standards, but not necessarily maximum performance. Per Reddit posts, this seems like a BS line they say to everyone. It feels very bait & switch or reselling of refurb units as new. Either way, I canceled my order (3 days after it was never shipped) and went to Amazon. You get what you pay for.

I have seen a lot of responses, but only two who have stated they have received the TVs, but none speaking of the many other items advertised on the site. No address so I am very suspicious and no contact names. Ran a Google Phishing on https :// abctvs, com and came up with nothing serious, but nothing else. A couple other sites selling TVs cheap were rejected due to redirecting. This site also has no business address or verification with online companies. It does have a secure HTTPS that makes transactions safe.
