I am not sure if this fits best in here, if not please move it to the appropriate section.
Since Black Friday is around the corner, many people are waiting to get themselves some decent deals specially from Amazon, the sad part that they don't tell you is that the prices Amazon shows are misleading to say the least.
This
Article on Forbes.com talks about the "The first deals of Black Friday 2019".
The first deal in that article states:
Apple iPhone XS, 256GB, Space Gray - Fully Unlocked (Renewed) - $749.92 (save $550 on original price) - shop deal now
That sounds like a great deal to be honest, however,the only truthful piece of information in this (as far the numbers are concerned) is that it does sell for $749.92, while everything else is B.S.
But how do you know how much are you actually saving?
Using a proper price tracker ( a piece of software that keeps track of history prices ) allows you to see the price history and compare it to current prices, I personally use Keepa ( DYOR and use at your own risk of course) but you can pretty much use any price tracker you feel comfortable with, and this is an example of the same item that allegedly has a 43% discount.
You can clearly see that for instance that the price back in July was only 899.99$ , last month it was only 846.99$ , which means if you buy it now you are only actually getting 846.99 - 749.92 = 97.07$ discount as opposed to the alleged 550$ savings , and that's less than 12% discount which is no way near the fake 43% listed on Amazon.
During black Friday discounts you will notice many similar examples , where they show you a 50% discount when it's really just 5% or no discount at all, of course they don't randomly put these numbers, that iPhone was probably sold for $1299 sometime around it's announcement or a bit later, but using it as a reference of today with that whooping 43% fake discount is both deceiving and misleading IMO.
