Amazon Median Pricing percentage discounts

Amazon makes no sense to me (as a buyer or a seller) when it comes to buy boxes and prices.

I have ones where it wants me to compete against myself (FBA and FBM on same ASIN and obviously I charge more for FBA)

Sometimes when I go into the “sale” price that I have set is my FBM and its proudly telling customers that its the cheapest its been in 30 days and showing my FBA price as the “was” price and my FBM price as the “sale” price.

All of these are items that I sell by myself on the ASIN.

At the “i” on the popup beside the was price it says “This is the median selling price paid by customers for a product on Amazon.co.uk (excluding promotional prices). For Amazon Fresh offers, the price is calculated as the median price offered locally for at least seven days of the last 90 days (excluding promotional prices).”

Therefore:

I’m guessing to make customers believe the product is on sale, and that they should buy now, or convincing them that the price is low and they’re getting a good deal

Median is a simplified way of working out a mid range, basically you put all the prices from highest to lowest in a row, and you find the middle number (for instance if you have 11 numbers, then you go to the 6th one on the list) that number is the median. (if you have 10 numbers, then you go to the 5th and 6th, add them together and divide them by 2)

The Median is taken from the prices the customers have paid over the last 90 days, so sadly we will never have access to that information, you can only assume that the bots can do maths and that they are actually calculating the median (and not the mean or the average lol)
