Dang! - Thank you very much!
This has been discussed here before
(that you couldn't see the actual selling price) but I never saw this solution mentioned.
(or I missed it or just forgot!)
There must be a "time-limit" as to how far back these search results go?
I couldn't find some previous purchases from a few years back. It seems likely it's a ~12 month look-back.
The other weird thing is, about 5 years ago, when I bought an vintage P, the seller allowed me time to transfer funds around, by artificially inflating the price -by double. (my buddy knew I was going to buy it, saw the new price and freaked out, calling me in a panic

)
But for a long time - the link to that bass after I bought it still showed the inflated price..
Now when I bring it up, it from the link, it does show the actual purchase price... ¯\_(ツ)_/¯
