Hey dr-red, heres another great idea that I use. Find the nearest college to you that has housing. When school lets out for the year, bring a van, truck or what ever to the school and start packing it up with the stuff the students just do not want to take with them.
Also, Flea markets are great. But you guys are going about it sort of wrong. Well thats my opinion anyways. First thing to do is goto the flea market, not to sell, but to do research. Look at what people are selling, look at where the customers are congregating, talk to the vendors (no they wont tell you where they get their stuff so do not ask), make notes. See what is lacking.
Different people will tell you different things. For example, you have one vendor that says online to sell what people want and stay away from needs, while others may say the opposite. It all depends on what people seriously want, what type of flea market it is, is it outdoors, indoors, whats the weather like, whats the area demographics. Go to a few different flea markets and do the research.
It took me 10 different flea markets at different locations this year to figure out what sells well at 1 particular flea market. I watched it, researched it and will be implementing it myself once I find a reliable supplier for what I need.
I am sorry that one of you had a bad experience with the dollhouse and all, but don't knock all flea markets because of 1 day of bad experiences. They can be fun if you find the right ones.
