1. People will buy anything if the price is right.
2. Even if the price is right, they'll ask to pay you less.
3. There is no way to keep clothes organized when 20 people are rummaging through them at any given moment.
4. You will do 80 percent of your day's sales in the first hour.
5. Do not open the garage door until you are ready to sell.
6. People actually do buy cassette tapes (and to think I scoffed at my father for putting them out there).
7. People do not buy used toilet plungers (I laughed at my mother when she brought it out, I teased her with it half way through and I taunted her when it was one of the only items still sitting unsold at the end of the day). What was she thinking anyway???
8. There are people who are really in need of bargain-basement-priced decent used clothes for their kids and they are grateful and appreciative that you spent your Saturday sitting in a driveway (I undercharged every one of them).
9. Doing a family sale is the way to go -- you have more items to sell (which draws the buyers) and more hands to help. Keeping the money separate was kind of a pain though.
10. They're profitable. I pocketed over $350. Not bad pay for a couple days of work.

Believe it or not, I sold almost everything. I brought back two small containers of things. I'd have brought more clothes back, but a woman stopped and handed us a piece of paper saying that they would come and pick up any donations of clothing and/or toys we might have left over. They collect the donations and distribute them at Christmas time to needy families for free. We were all for that & I left most of my remaining baby and kid clothes and shoes for them.

So, I made some money, I helped some people who really needed it and I gained lots of basement storage space. Live and learn.
