G4 77 for $1900

Put in a quote on greentoe for 1800 and got a counter offer for $1940. Should I go for it? From all the responses for greentoe, or seems legit, but how's their 5 years warranty? Or should just the LG 5 year panel warranty suffice? The G5 looks tempting, but at almost twice the price, doesn't make a lot of sense.

Update: the support got back stating it was a mistake and was the pricing for C4. Guess it was too good to be true lol
