As a kid I used to frequent the Goodwill Electronics Waste store in Santa Ana, you could kit entire machines together for just a few twenties; the value of the parts compared to their once retail price was maybe 5 or 10 % of the MSRP even back then.
I went back two years ago to satisfy my nostalgia and found the place now filled with 3-4 year old product that hovered around the cost to buy the same parts on an online vendor of some sort, and any of the interestingly-old-but-useless equipment like old ISA video cards/early PCI stuff/AT keyboards/anything beige was marked up so huge by some staffer that mistook vintage for value that it was absolutely impossible to find anything worth buying.
Water damaged gameboy faded-grey cartridge? 200 dollars.
Pentium 3 e-Machine? 300 dollars.
480 line composite security camera with no power supply and no hope that it will ever do anything useful ever again in the future?
Does it have a beige or metal casing? 200 dollars.
I think I ended up finding some cheap molex-style 12v fan to buy for a few bucks (more than any online retailer, still), but it was mostly just a guilt purchase to help support the Goodwill.
I left incredibly disappointed.
I just wonder if maybe there are a bunch of people out there willing to pay those prices for some reason.
The people giving away their time at the register are doing it to feel good about themselves, to "give back", not because they are interested in or have competence in retail. The product being traded between buyer and seller is smug narcissistic self-satisfaction and moving anything at all is irrelevant.
I've volunteered at a similar outfit as a driver and tried to offer some assistance with realistic valuation for the ikea shit that was wasting 60% of the warehouse, but it wasn't welcomed. $300 for a Billy is "reasonable" and it's for a "good cause".
Problem is the same everywhere regardless of pay structure, charity is used to as a crutch to wave off all criticism, a lack of retail competence, and any willingness to learn.
Having grown up in the UK I always assumed goodwill stores were just what we call charity shops over here, you’ll find three or four on most high streets, all run by different charities and staffed by volunteers with any proceeds going to fund the charity’s work.
Yes, awareness of competing buyers (and better market access of the seller) erases arbitrage opportunities. Venues that price at a steal compared to the broader market are not in a stable equilibrium.
