I think you are seeing a local phenomenon, maybe?
This is the time of year sellers try to jack up prices to take advantage of buyers' tax return money. But up here (Seattle) I have seen a much smaller rise in prices than I remember from the two previous years. Also, I have picked up a few things off of Ebay with BIN for 1/2 to 1/4 the normal auction selling price.
Now, with all of that being said, I did sell a large number of rejuvenator adaptors over the last couple of weeks. More than I had sold in the previous nine months combined. But I attribute that to a buying frenzy due to rejuvenation, tube swaps, and monitor repair in general being discussed by so many new collectors.
