When I was going to buy a TV in 2018 I had settled on a really good TV in 55" (XE93/X930E) for £1000 preowned, only used for a month or two.
Then we noticed the 65" ZD9/Z9D (minimum size for the model) display models on the shop system went to clearance price finally (Released in September 2016), its one of if not the best HDR LCD ever made so I was excited but it was still far too much for me, £1300 was my limit. Most were boxed up in the back of the shops and there were only like 27 units left across the UK in total, it went to £2699, then £1999 and then finally £1399 and I went to buy it, but at the same exact time by washing machine broke and I really needed a new one so I didn't have enough money anymore and there wasn't enough time to open a credit account as there were only 3 left in the UK.
I called my dad to ask for help with the washing machine and TV purchase and he agreed because he's awesome and said "I'll up tomorrow to do it with you" thinking that was reasonable and I was like "uhhh I need to buy it today Dad or it will be gone" and he just thought I was being impatient so he came up the next day.
Of course they were all gone off the system but I noticed this weird other model when I was searching throughout the day to make sure there were no returns, turns out it was a mislabelled entry in the system and it was in the fucking store I was in! Best thing was it was a return from a guy who was unhappy with how a specific app didnt work on Android OS (Wasn't Android TV yet) and nothing else, so the panel itself was perfect condition, just no original feet/stand.
Ended up paying like £1200 after discounts and I'm still amazed by the TV to this day, I'm writing this message on it.
I've since been massively beaten in awesome TV deals by my friend who got a 85ZG9 for £800 this year due to Covid putting everything on pause (including returning floor models to the depot) and letting the auto clearance price system go out of control and keep discounting it. The RRP is £13,999.
