If you start buying a fair amount of storage units, you will not have the time to list everything yourself.  I use multiple eBay selling assistants to sell my eBay items.  When you start buying units consistently, a lot of your time is taken just digging through the stuff and sorting it out.  You will quickly discover that you do not have time to buy and clean out all your units, take the pictures, list the stuff on eBay, answer all the questions, deal with sending invoices and making sure you get paid, and then shipping the items.  I have worked out a deal with my sellers to do all of this for me for a flat 35% of the gross sale, not including shipping.  They are happy because they have a lot of basically FREE inventory to sell, and I'm happy because I just take over boxes of junk.......ummm, I mean "Treasures", and money is consistently getting deposited in my Paypal account.  Sure, I'm basically losing one third of my money, but with the volume I'm doing, and no headaches on my end babysitting ads and dealing with unreasonable purchasers, it's well worth it to me.  Trust me, if you are going to buy storage units in any volume at all, you do not have the time to chase every single nickel!

I think if I consistently found everything they find and didn't have to waste my time hauling off garbage and the rest of the contents, I could be retired by now!  Fun show to watch, but I hope nobody watching the show just expects to jump in and find a gun in 3 out of 4 units, or to find a restored antique copper cash register in a unit full of junk.  Great entertainment, but leaves out a lot of the work involved!
