A lot of sellers don't use tracking services, as they add extra costs on and there is no point in tracking a really cheap item anyway, as it won't hurt anyone too much if it goes missing. It's not the sign of a scam if they didn't track the item.
what kind of info was listed ? why didn't you contact the seller B4 buying to verify the item ? the only way that is "legit" is if the tv screen is broken ; most tv screens are not available to buy separately, and even if you find one, it costs more than the tv......I just now looked and did not find that tv
Often they make their profit from shipping charges higher than the sale price. This may be more common on Amazon.
As far as what your getting, expect it to be like a white elephant gift, possibly unusable as a TV.
You won't know until it arrives. What is the seller's history?
With E-bay, you take your chances. Can a 55" TV even BE shipped via USPS? You know the saying: "if sounds too good to be true, it probably is."
Refurbished means it is not new. It has been broken and fitted with new parts.
