People who do not know who I am or unfamiliar with my work always ask such a question. The usual response is, "I can go to my local (Insert General Electronics Store/Conglomerate) and ask them myself!" Well let me tell you. I've worked for many conglomerates like Staples and Best Buy over the years, and I can tell you that less than 10% will give you some of the crucial information, and less than 2% will be able to explain, in-depth, why certain features were developed, and why certain things don't look right to the average person.
There are things that are not public knowledge, and there are more things not taught normally. There is just some knowledge that has to be learned through research, and I'm here to help you alleviate some of this time-consuming activity.

(#7) Resolution
Yeah. yeah, you've heard the spiel over and over about how much better 1080p is, and how much the new 4k Ultra HD is great, they probably never really told you the difference.
While the overall is obvious between MOST DVD/Programming and HD Blu-Ray/Programming, sometimes, it's the finer details that we always miss.
For example: In Die Hard 2, you see Bruce Willis crawling through ventilation. From the stage lighting, you can see his forehead glistening, notating sweat. In higher resolution HD, you can count the beads of sweat on his forehead.
While 4k has yet to see more than just a very small handful of movies and only 2 different players in circulation for sale, be sure that if you choose to pursue this endeavor, anything above 50" screens are what you're going to need to see any differences.

(#1) Get The Great Without Paying Great
Here's a little buying secret that most employees are also oblivious to. Major brands like Sony, Panasonic and Samsung run abnormally big sales (imposed onto distribution retailers) to get rid of inventory.
Also, pay attention to certain places for ridiculous clearance sales as well.
First off, let's start with the clearances. While we're all familiar with what it means, there are a couple companies to monitor if you want the really big clearances (sorry for anyone who lives outside the US):
Best Buy: After a television goes on clearance, BB will drop the price every 4 months after by about an additional 5%. After 1 year, it drops to bottom-line.
Staples: Being mainly an office supply store and rarely anything else, bigger Staples stores will always have better quality TV's left over from the previous year, and the clearance prices shoot below 50%. The smaller stores will have more basic models between 20 and 32 inches.
Sears: A very unexpected place that is never associated with the word "quality" in the past. However, since 2010, they have shaken off contracts with lower brands and upped onto top brand contracts, providing a good amount of great televisions.
However, the consensus on Sears is still low in the recent years so they don't sell off as well, resulting in a lot of clearance TV's, especially in the smaller stores, where discontinuation comes sooner than the larger ones. Anyone who shops at Sears actually only go for the highest quality Samsung and Sony items.
The mid-level models (basically 32-46 inch HDTVs) usually end up on clearance with 20+% off. Once a TV goes on clearance in these stores, their prices drop every month, and every other week after the 2nd month. It hits rock bottom prices within 4-6 months of hitting clearance.
Okay, now for the more regular stuff. Let's face it, we can't always catch the clearance, if ever at all. Well, here's the next best thing, especially if you want to get it newer from release. There are 3 different types of sales that you want to look out for in the life of a TV:
First week of release.
Manufacturer's Sale
Clearance
If you can't get to the TV's opening week sale, you can sometimes get a larger, if not equal, sale with the Manufacturer's Sale. These are rare, and rarely happen more than once during a TV generation's 3-6 month cycle of distribution. These sales run anywhere between 30-60% off. These sales are unannounced, very short, not advertised (often), and sometimes IS the largest sale, depending on the model. (Example: In June of 2013, the 46", 240Hz Samsung 3D SMART TV, at a retail of $1,400 went on a Manufacturer's Sale for only $650 for two days only.)
