Garage Sale or yard sale
   Time to make some quick cash. Earn money selling what you don't want anyway. Generate a fast income. Kill two birds with one stone. Clean up and get rid of stuff that you don't need and make some money at the same time. If you need help make it a family affair. But here is the trick to really make more money with it...
I overheard some people talking about the weekly summer garage sale that they had.
   Apparently they sold almost all of the things that they could possibly sell from their home and garage and then found deals on stuff at flea markets to add to the weekly garage sale. It got to the point where some folks would drive by and stop to look and come back the next week again. If you can get away with it in your neighborhood then what the heck?
Why not have a garage sale? You'll enjoy the extra income.

Plan ahead.
   You'll need change coins and bills. If you have tarps available keep them put away and handy nearby to cover the stuff in case of sudden bad weather. Use an extension cord for electrical items to prove that they do function properly. Round up some tables to display the items.
   Antiques are a big seller, even if they are broken or in bad shape. What is junk to one person is a goldmine to another. Memorabilia of all sorts sell really well. You can sell more of an item if it is the season for it. As an example you can sell "Back To School" things at the end of the summer, and beach toys in the late spring early summer. etc. You get the idea..

Advertise
   You can make flyers on your home computer and put them up locally.
The local newspaper might offer cheap of free ads.
Craigslist has a category called "Garage and Moving Sales" and it is free to put your ad there. Your church or local clubs or groups have news pamphlets and flyers that you might put an ad on. Hmm, Free lemonade?

   E-mail! Aha! It's as cheap as can be. Send a newsletter style e-mail to everyone on your contact list who lives nearby. You might want to mention the general categories of items for sale.
    The more variety the better the response will be. In all of my endeavors I have found that to succeed in getting a lot of people to come to a performance or party or event, I needed to do more work to remind people and reach more people than would be expected.
