My personal suggestion would be to do like we do at work. Throw away the bottom
and top 10% using the average of the middle 80%.
The bottom, because there are numerous stores list 1 item at less then .01 to
get people there then the remainder of the same item is about average, or above
average. Then there are those that use their store to hold items, Ive seen .05
items for "sale" at $500.00

What do people use the average of the "Current items for sale" info for? I would
think that the 6 month sales average info is much more important. It has been
brought up here many times and I don't understand why people don't use
the 6 month sales average instead?
I am asking this not to be snarky in any way, I am just wondering if maybe I
am not seeing the importance of that information and thus missing out on the
use of it.

Both are useful.
When you want to set a price on a item (buying or selling), you look at how much
similar items were sold for in the recent past but you also look at how much
it can be bought now. And how many were sold and how many are for sale now.
Say something sold for $5 last months but you can’t find some for sale below
$6 now. What help does the past sales give you? Will you wait until the price
goes below $6 again? What if that never happens?
Or the other way around, something sold for $6 but now you can easily find it
for $5. If you’re a seller, if you price it at $6, you won’t sell yours before
all the ones at $5 are sold ; and that could take a long time. And if you’re
a buyer, if you only check the sold price, you’ll be happy buying at $6 when
you could easily have had the item for $5.
All info is useful.

median is already there via the quantity average.

No. Median and quantity average are totally different notions.
(E.g. prices 2x$1, 1x$4, 1x$5, 1x$10, lot average = (1+4+5+10)/4 = $5, qty average
= (1+1+4+5+10)/5 = $4.2, median = the 3rd price = $4.)
Still, you can find the median by looking at the “raw” data and adding all the
quantities until you get to half the total quantity.

Problem is more, people desperately hang on to non weighted avg prices in stead
of their weighted qty avg.

Problem is people hanging on the price guide

| I think a big issue is when someone accidentally (I assume) lists a cheap 50
pence item at £49 (or similar) by mistake, this does impact the avg greatly.
Seen it loads of times.

Interesting idea and it does solve a problem. Another method could be taking
the median rather than the mean. Or the seller could have the option to select
his default preference (eg. Median or Mean Value).

median is already there via the quantity average.
it is stupid to take out the lowest and highest because you cant cancel these,
as they are legit buyable offers.
Furthermore would you delete a part with 4.5 cent as lowest, but dont do to one
thats exactly 5 cent?
The highest parts dont have much impact on the price, because one part at 20
dollars,
is not much recognizable in a complete offer from 20000 parts from 10-15 cent.
Problem is more, people desperately hang on to non weighted avg prices in stead
of their weighted qty avg.
