By buying items from a second hand store you are helping prevent those items from going to the trash and landfill!
Or at least one of the very few left of its kind - no one will show up wearing the same outfit. If you buy a piece of furniture that will be unique as well!
Some thrift stores are filled with vintage furniture - which can often mean great quality. Since many furniture places are on backorder, thrifting is a great way to get your items right away!
Weekends are fairly busy and some thrift stores are closed on Sundays so if you can go during the week, you might have better luck!
Before you shop, why not fill a box with some donations? You can drop it off at the thrift store and pop in to shop as well - it's like giving back double time!
