I was using Macklemore's "Thrift Shop" for a ring tone for a while but I got tired of it pretty quick. I even changed the notification settings on my phone so people don't recognize the classic Ebay "cha-ching" when I get paid. 

Yes, it can be sold. Some markets don't allow it but others do.

Some folks might be buying the porn cause they don't want their cookies and IP address collected and tracked for visiting "free" porn sites.

It tends to happen for me when an item goes hot and heavy on auction and gets up in the few hundred dollar range. Sometimes I think people get in bidding wars or try to run each other up on Ebay. Other times I think it's someone who sells the same product using a ghost account to purposely mess with my auction.

Yes you can make a living at this but you will work your ever loving a$$ off! This is my only source of income so it can be done but it's a ball-buster. I can imagine a gifted person with incredible work ethic, sales skills, marketing skills, organization skills and in a large city with plenty of auctions and a large customer base with disposable income could make very good money. Like dbr831 mentioned, when doing this full time I really can't wait around for the great units. I have to buy every week and if it looks like it will make money I got to buy it. The bad thing about that is a person can get tied up in $100 units that only make $250 and get trapped in a "money in, money out" wheel until you get lucky and one of those $100 units scores $1,000-$2,000.

Part timers or hobbyist have the luxury of waiting around all month or several months for that one good unit. The bad thing is it looks good to everybody so a great looking unit might end up costing $2,500 and make $5,000 or it might only make $2,500 cause it wasn't as good as it looked.

The guys who look like they are making the most bank are the ones selling the imported fresh fruits & vegetables. Second would be the folks selling boxed & canned foods, soap, shampoo, detergent, etc, etc.
I think that side has become less profitable though since more people are going to pallet auctions. Years ago there would only be 2 guys selling that stuff, now there will be 10-12 people selling it.
Relatively same customer base, 5 to 6 times the vendors now.

I'm not going to give out the four things I look for to bid on a unit, but I will tell you four things I look for so I don't bid on a unit.

1. Rodent sign; droppings, urine smell, petrified carcasses.
2. Heavy pet sign; urine/b.o. smell, hair.
3. Rummaged boxes.
4. Mold/mildew.

I would add cigarette smell but then I if I did that I wouldn't buy any units so I got to pick my battles...

Here is another one I can only assume is a craigslist crazy.....

Maybe if your asking $25 for an item that is readily available (not discontinued, still sold) you might want to remove the $12.99 price tag......just a thought.

He just has his haggle price built in, that's all. 

I don't think I signed into the WWW until 2001! LOL!! But I do remember looking over my friends shoulder when he started in 1995.
