Do you have clothes that you want to get rid of but don't want to deal with selling them, yardsaling, or storing them somewhere?
Do you have books that you don't know what to do with but you are tired of looking at them?
How about food you bought but don't like and won't ever use?
Then donate them!
Take them to places that will give you a receipt so you can deduct the value off of your taxes at the end of the year. Call places like Purple Heart that will come pick your items up. If you've got a vehicle to get rid of, call Vehicles for Change. Take the items to thrift stores and churches.
Why is this frugal?
1. You are giving other people the opportunity to purchase items at a lower cost to them. Many of your items end up at thrift stores or are donated to less fortunate people.
2. You aren't wasting your precious time sitting at a yardsale waiting for people to come buy your stuff. Only to have most of your items go unpurchased and back into your house.
3. You get the cash in your hand after you do your taxes and didn't really have to work for it.
Just remember to keep all of your donation receipts in the event that you get audited!
