When I first got into the buisness, I learned the hard way several times about properly tying something down. Unlike most of the posters here, I emphasize delivery on all my craigslist posts. I really feel like this has increased my sales, and puts me far ahead of others who wont offer any kind of delivery. In fact me delivering an item a person has only seen in craigslist pictures is a regular thing for me. So far (100+ deliverys i'd estimate) it has not back fired. But I also make sure my pictures are spot on, and make sure the person is extremely sure this is what they want.

Same as Movieman, I sell the bibles/cds/pictures etc. Even the black jesus stuff sells eventually. Theres just something that doesnt feel right about throwing a bible away, but I can live with selling it. 

I was a novice in this field until very recently. Paid $100 bucks for a 'medical locker' honestly it looked like someone had died and they stuck their hospital room in this locker. Beyond the 20 or so boxes filled with pills and the random extras (CD Players/trash cans/cleaning supplies), there were three extra sized wheelchairs, a hospital bed, an Arjo Hoist lift type machine. Heres how the selling broke down:

Wheelchairs: $40-50 bucks each, they were very nice in great shape and sold fairly quickly. (All three in a weeks time)
Hospital Bed: Sold for $350 bucks! It was electric, had head/foot and a brand new in the box mattress topper. Sold extremely slowly. No calls/texts after two or three weeks of being on craigslist, but the one guy that did call bought it.
Hoist Lift: Still in the process of trying to sell. These things are extremely expensive, I have mine listed on craigslist for $500 - but not a single call/text after two or three weeks.

I was nervous when I bought it, but you cant argue with the profit. The high end health care items you will sit on for a while, but can be a nice pay off when you do find a buyer.

No rules about kids here, but we have a few guys who like to bring their dogs (small ones). I heard this morning one of the local runs started putting a "No Pets" line in the ad. 

$350 bucks. Alot of boxes that turned out to be food, was lucky to break even.

Cheap here if you know the ones to go to, I just bought 4 units for a total of $117. Lots of boxes in some, heavy furniture in others. But all good deals.

Heh, when I first started doing yardsales, some stray cat had her babies behind the shed of my house. There were three total, I put them in a box marked $5 each and sold every one by the days end.

Man wish I had that problem. I am up to buying 2-3 lockers a week now, my issue has been selling yardsale/flea market type items. I have a shed full and hold yard sales every week, but I am seriously worried about my space situation with the constent flow of furniture I have coming in too.
