This is the way we calculate it:
We take the average value for all shoplinks. And this is not a weighted value but the average of the available shoplinks.
If no shoplinks are available anymore the price of the last known shoplinks will be stored.
The value will be adjusted after a shoplink is verified. Meaning the shoplink is visible and working but the average value will only change when a moderator or admin has check the link. This is put into place to avoid fake links that try to adjust the average value displayed on Whiskybase.
Hey, i came back here, to see that die Average Price is now finally the choosen one :- )
In general I can live with that. But I have a question:
The average is sometimes far to overpriced (in my opinion) and because of variaty of shops and countries there might be offers conciderably cheaper in the shoplist.
It was mentioned that also the shipping costs have to be considered and that the average price tries to level that out and that the shoplink has to be veryfied to stop manipulation. Completely signed. Good Points, especially to find a "real" average value!
But it is very time-consuming to visit every page of Whisky to check the variation of offers if you maybe try to find out the real value of your collection. You have go to the individual entry, scroll down to the links and find out, how big the price spread is.
Example for variaty is Ardbeg Ardbog (21.06.2017), ~90€ Euro difference from average to min marketplace price / ~60€ to shoplinks.
Would it be manageable to also integrate the recent "min" and "max" value for a bottle? (From the shoplinks / maybe + marketplace)?
To evaluate the real value of the bottle/your collection a combo of these three key indicators, by showing the spread of all offers, might be a good thing.
Like for the Ardbeg Ardbog:
Min Value (with marketplace) / Average Value / Max Value
119 € / 201,70 € / 458 €
If there is absolutly no link available, every Price would the same "historical price"
And they would be all the same, if there is only one offe available.
I think this migth help to support very good offers on your marketplace and the whole net and give the users here a little bit more overview over the value of bottles and their collection. And I read that there might be a feature of external auction values in the future, that might be a good fourth indicatior...
Hope I could descripe my idea enough :- )
What you think?
