Prices here and on ebay.....what do you notice/think?

Forgive me, but I am new at this high-end audio game...only been at it for 50 years, both in the business and as a consumer. 
 I do not know, maybe it is a side effect of Covid, but some of the prices people are asking are just not in keeping with what a unit is worth or what they have sold for recently.  On all sites, the best reference for price is sold items, what an item actually sold for rather than a hopeful listing price.  But the proof is in the sales, or lack of them.  In being active on this site and ebay, some of the current prices are ...well surprising.  I guess caveat emptor is very timely.   Is this something any of you have noticed or?
