1. If you aren't in town or too close to a main road, consider borrowing a friend's yard for the day. Luckily, we aren't too far from the main road so a number of signs did the trick.
2. Have large consistent signage. We used red signs to grab attention and wrote with large letters. That's one of my petpeeves is to see a sign but not be able to read it until you're right up on it so we did that and added arrows. I add our street name on the first few signs just in case some signs fell down.
3. Start early. I ended up getting up at 5 which just gave us enough time to start at 7. In retrospect, I would have liked to have started earlier since the early birds were the ones who really bought most of our stuff. But after staying up late at work, it wasn't really an option.
4. I remember reading that people won't buy what you think they will and it is so true. I found it interesting to see what people were drawn to and I didn't sell what I thought I would.
5. Put your larger pieces closer to the street. Having several large pieces, many tables, and a stainless steel grill really helped draw people in.
6. Know what you can and can't part with for a certain price. There were about two pieces for us that we knew we wanted to sell at a certain price point. Besides that, we bartered like crazy. About 95% of people asked for a better deal on everything and about 95% of time I said yes. I just wanted to get rid of stuff. Although it may be hard to part with things [especially when you know you spent more on it], I find it's easier to just get rid of it. I didn't want to stare at things thinking I should've said yes. And if you don't like their price, come back with something you can manage. People expect to barter.
7. Overprice your crap. I did this expecting people would try to barter and I'm so glad I did. I didn't overprice it like crazy because people would take two looks and leave but I left room to go down without it hurting so much. I had no idea how much people try haggling so that made me happy.
8. Have change. We had $100 in 1's, 5's and 10's. I priced everything at $1 or more [no 25 cents or anything like that] but we still had people haggle down into the area with change so it doesn't hurt to have some on hand. We just raided our change jar.
9. Have packaging on hand. We had plastic bags and a roll of bubble wrap that people were thankful to have.
10. Set a breakdown time.
11. Style things like a store would. Use objects to create height and group things in odd numbers.
So that's what we learned, what worked and what didn't. Unfortunately, we still have plenty left thanks to me being called in so we will have to do this again soon. Unless you want to buy all my crap?
