When I lived in the city, I thought craigslist was a MIRACLE! It's still useful here, but seriously not a lot listed (like 8 items listed in the baby/kids section in a day, instead of 5 pages where I used to live, lol).
I have a junk email address that is not my name that I use for all "disposable" stuff, and my real email address that is my name is ONLY for real friends (the ones that don't forward me a bunch of junk all the time, that is). I would always use the junk email address to do stuff like craigslist. Other than that, sounds like you know what to do.
My husband used to call me the craigslist queen, lol. I got a large entertainment center / armoir thing which was really good, had 3 drawers, 5 shelves, and a place for dvd player and cable as well as a big screen TV...got it AND the TV for $100. The TV worked just fine. (I do not buy electronics generally because I don't want to be unpleasantly surprised....but in this case, I was happy to pay $100 for the entertainment center and the TV was just a free bonus). Donated both 4 years later to the guy who helped us move, as it wasn't the right dimensions for our new house. I got a like new graco high chair that I priced the same one at Babies R Us for $60 (sold 2 children later for 25), plus an unopened splat mat for $20. Bumbo seats for $15-20 (and sold later for 20-25). A play kitchen hardly used for $25. A Winnie the Pooh plush chair, a Tigger doll, a Pooh dining set, and placemat (all in the box or with tags---they changed their mind of themes) for $10. Some hard to find bits and pieces for my son's bedroom theme. A ride on train set that goes around the Christmas tree for $20. 3 toyboxes (one full of toys) for $10 each (I later sold 2 for 20 each, one for 30). 2 train tables for $20 each (sold one after he outgrew it for 20). A 7' prelit Christmas tree that was the exact width I wanted, the right tree, with a revolving stand for $40 (yep, it all works). My son's T-shaped bunk beds, with bunkie board, desk and cork bulletin board, dresser, book shelves, headboard for bottom bunk, and 3 drawers beneath the bottom bunk for $80. A coffee table for the playroom, a small tv stand, the list goes on and on.
Never once had an experience with a flake when buying or selling. Well, ONCE I was meeting a man at McDonalds to sell him my toybox. I chose the spot because it was close, populated, and my son could eat nuggets and play on the playground, I could drink a coke and read a book, if he was late. Not too inconvenient. He phoned my cell (I give out my cell when making arrangements to meet, but not my home number) and said he was not going to be able to make it. Asked if I would take it to his work (optometrist office 2 miles down the road) because he wasn't going to get his full lunch break that day. Since it was still a busy shopping strip, I brought it to the office and he gave me an extra $15 tip for delivery.
