Flyers
If you’re not tech-savvy, you can always get flyers made and hang them in local businesses and grocery stores. Be sure to include pull tags on the bottom with your name and phone number so people can easily reach you.
This is an especially good option if you have a lot of furniture to sell and you want to invite people to come and browse through it. Make sure to check with local management before hanging up any flyers and return in a few weeks to remove them.
