You may say this example is not realistic, but it's not that unrealistic
either. Check out item 6558. The avg used price of last 6 month sales is €0.023,
while the majority of the sales are for less as €0.02
If you look more closesly, you see a few sales at a high price, but not a lot.

It's my suggestion to change the calculation of avg price to use the 90-percentile
method. So only the 90 percent (lowest prices) are taken into account. That way,
the top 10-percent highest prices are not taken into account when calculating
the avg price.
To avoid weird behaviours, the rule could be in place only when there are 10
items sold/for sale.
Example would become an avg price of €0.10
Another somewhat more complex method would be the use the median. Not the mathematic
average, but the middle price: 50% of the sellers have a lower price, 50% of
the sellers have a higher price.
What do you guys think?

This suggestion comes up now and then, I am not in favour, as it makes the priceguide
less transparent but most of all it promotes the race to the bottom even more.
In a different kind of design, with a different role and usage for the priceguide,
I could be in favour. But the way Bricklink is set up now, I think sellers very
strongly evaluated based on their prices not being above average - at least that's
how I used to use Bricklink when I was a buyer. I think in the current design,
we need those quirky up-effects, not because they make for the most ideal and
scientifically sound kind of priceguide, but to balance things in a context where
down-effect already prevails.
What surprises me though is that you suggest it to include only the lowest. Why
not middle 90%? What you propose seems to me like a race to the bottom on top
of a race to the bottom.. That sounds like you prefer the priceguide showing
just low prices over accurate prices. I really don't think prices on Bricklink
are unfair at all considering all the work that goes into running a store.

In my opinion this wouldn't work!
They have this function on eBay and it is a nightmare to be honest.
The sellers have set their prices and if you don't want to pay the listed
price then you simply buy elsewhere.
I suppose if you want to make someone an offer you could do this via the quote
function and ask if they are prepare to sell for "x"
Bricklink needs to stay well clear of this.
Just my thoughts!

| Could an option (maybe this was suggested before?) be added that would allow
possible buyer to offer a price?
I would list an item with a price and a check box there would make this item
appear with a 'make an offer' options. Potential buyer would enter the
price he/she is willing to pay for an item. Seller receives this Quote and denies
or accepts this offer. If seller accepts it he then can add shipping quote and
send a quote (or something like that).

Hi Randy,
This is a great suggestion which I can fully support. It has happened to me a
couple of times that I missed a "note to seller".

| As a buyer on Bricklink
I sometimes have a seller requesting an "Order Item Removal Request"
on items the seller does not have in stock.
When the seller requests an "Order Item Removal Request"
can this request be sent to the buyers Bricklink Messages (presently it does
not).
This lack of notification from bricklink has caused many issues between buyers
and sellers

Is there any way to indicate that the list of sellers should only be from 'My
Favorite' stores? If there isn't any way to do this, then can I suggest
that this filter be added?
Besides being happy with specific Sellers and therefore wanting to use them again,
I've also found that when I'm trying to put together orders, the slightly
higher cost of the item is often offset by the savings on shipping by keeping
the order to a smaller number of sellers. I find that I'm often scrolling
through the list looking for those specific sellers that I want on this batch
of orders.
