Maybe I'm a little late to the party on this one...but have you heard of Yard Sale Treasure Map? It's an amazing mapping tool that combines Google Maps with Craigslist. It culls the yard sale listings from Craigslist and create an interactive map with all the info you need to hit the sales in your area.
Let's say you wanna hit some yard sales on the upcoming Saturday. Just type in your address or zip code, your desired driving radius, click 'Saturday' on the drop down list and hit Search. The map of your area then loads with pinpoints of all the sales. Click on the pinpoint to get a description of the sale.
Once again...the internet is simply amazing! I love this!
TimeSavingTutorials.com has created a nice video tutorial of YSTM which covers most of the basic functionality of this tool.
There are countless websites today that claim to be the “place to go” on the web to find and post garage sales. But let’s be honest… there is only one globally accepted online source for garage sale ads… Craigslist! Not only is Craigslist a wonderful resource, it is also absolutely free! So honestly, why bother posting your ad anywhere else online?
YSTM doesn't make you create an account to log into or try to scam you into posting your sale explicitly in a way that no other sites can access your ad. They encourage you to post your ads on Craigslist because that’s where your ads will get the most visibility.
Hot Tip: when posting your yard sale on Craigslist, add your full address including city, state and zip. The system needs the info to correctly add your sale to the map.
