Never again. We don't get enough traffic at ours (either our house or the in-laws) to make it even remotely worth the effort.
ITA!! It's not that we don't get enough traffic, as we get people all day. It's the people who come to them these days that are the problem!
We used to have a yard sale once a year, when the kids were growing up, in the 1990's. I would set up tables in our garage a few weeks in advance, then go thru each room in the house sorting out the stuff we wanted to get rid of. Then we cleaned and priced everything, and put them on the tables. The morning of the sale we would drag the tables into the yard, and did very well. We priced low, and took reasonable offers, and then after 12 noon announced that everything would be 1/2 price. (There was never very much left by then, and I just didn't want to drag it back in the house.) We would make anywhere from $300 - $600, depending on what we had. It would be a fun day, and the buyers were so nice.
Well, we did some redecorating a few years ago and decided to have another yard sale. It was a nightmare. People wanted to nickle and dime everything - even stuff I had marked for a quarter!!! We had 3 women fighting over some baskets, several people try to walk off with things, and when I sold a soccer house flag to one woman for fifty cents, another came over to me to say she had been looking at it before and demanded I give it to her instead as she "saw it first"!!!
I thought that may have been a "fluke" year, but we had one again last year and the same thing happened. I'm thinking it may be the economy, but I really had things priced low, and still was taking reasonable offers for things, but wasn't planning to give things away for free!! I ended up ending the sale early, boxing it all up, and driving it to Salvation Army to donate. So that's what I do now - donate!!
Good luck and hope you do well!
