I've done Craig's List way too often. Somethings that I've bought - I have never used but maybe some day I will. Since I've gotten more than my fair share of deals here's the Tricks that I've used. Best one, Offer $10 more for the item - put that in the subject.
$50 for a spike aerator AND 6' blade - The kid put it on CL in the morning and he had literary had hundreds of replies and I offered $60 in the subject line (about lunch time). I also have given extra money after the deals... Ended up after talking to the kid for a while, giving him an extra $20. Sold the spike aerator for $260. Still use the blade.
$200 for a cutting torch, 50' of hoses; goggles; strikers; 2 acetylene tanks; and an O2 tank - This one I wrote; "NC State wants to buy your tank"... which was true, I use it at work. I also gave him and extra $20. So many people wanted to buy the tank. I told him that most of those people were only going to resell it at a higher price, Thankfully, He did graduate from NC State (took a shot in the dark!!) Would have backfired if he went to UNC!!!
I have over 15 or so purchases from Craig's List - One warning, If you do not know how to weld, you better learn how to. Most of the equipment needed some TLC... $50 for a 5' rear blade - the connection was a hack weld job. My repair was only slightly better but has held and I still use it.
One last one, Got this for $150... sweet old guy. I love talking and meeting people that I've done business with from CL... many times, I've spent an hour or so talking about old times. I end up giving him $180 for it... You do need to drop everything to chase after the deals.
