I did contact one in olx (then), and it was significantly cheaper than Abenson price which was about 93k 5 years ago, but I got it at 78k cash. He also explained to me that the reason for all these olx sellers selling lower than SRP is that they give up a large part of their commission to get the sale.
In any case, I know now what you mean by gray market; I just always thought of it like HANCARS for Starex or Caloocan Sales Center for Big Bikes, but you cannot bring those to the casa or need to pay a registration fee to get serviced (e.g. BMW).
Someone also posted here that they can keep the price low due to ordering in large amount. Something the big appliance store can't match. (Try to back read a few pages).
Mine is LG and they are honoring the warranty, tech came in today to replace the panel due to banding.
But so happen they brought in 65" panel, mine is 55". Not sure where is the disconnect on their documentation.
They are coming back tomorrow to put in the right one.
