Ive bought bulk lots on EBay of 500 to 1000 cd collections rip them then sell them back on EBay usually for more then I paid.
I used to do the same thing on eBay but with Software & Printer Cartridges (HP in particular). FULL TIME I mean, like, many hours not just casual stuff. With the HP Cartridges it was very common that a seller would list without Model (or "Part") # I could tell what it was from the boxes so I'd bid and win the auctions at absurdly low prices then put my own ad up Buy It Now for what I knew they sold for on a regular basis and after having told the seller of that initial auction "
Wait to ship while I determine which of my offices needs these the most" lol, faking like I was some MultiNational Conglomerate, I'd have that initial auction seller ship straight to my buyer and never even touch the things.
Most normally I'd take shipment though then ship out again...only when I could be totally sure they was Brand New In Sealed and undamaged Boxes, hadn't been exposed to intense heat....would I do the No Touch Flip.
Sage Software Accounting, 5 User Box within a year I'd flip about 12 of those for profit of around $185 each time, just on relisting and selling that software alone
plus there was a $300 Rebate on the software through Sage so it was criminal how much I'd make on ads put up by sellers who did not specify they had 5 User Box as opposed to Single User....only thing that differentiated was a small red sticker on front of box.
The HP Printer Carts were more amazing though, easy money, like an easy reliable Harvest...my Buy It Now ads wouldn't last 24 hours usually. The Sage 5 User Flip, $140 to as much as $250 profit on the initial resale + the $300 Rebate (
when it could be gotten, one had to battle the Rebate House for it....at times) was more like Lightning Striking.....averaged only about 1 per month of those.
My Biggest CD Purchase on eBay was 20 or so Bootleg Live Recordings....Hendrix, Dylan, UFO at Long Beach....Pink Floyd show at Montreal when Roger halted Comfortably Numb to cuss out the asshole lighting Firecrackers...
I enjoyed reading of what was a very very clever and impressive path taken CHOP by a music connoisseur to creating an AudioPhiles Dream collection of Lossless music.....may have not been a waste of time....strange stuff happens on this planet.
To me it wasn't a waste of time regardless cuz you love music as do many others and you managed to create an amazing archive of very high quality that.
