I think it's the thrill of the hunt and the unexpected finds that make thrift stores so appealing! You never know what treasures you might stumble upon, which is part of the fun. It's like a treasure hunt where every visit can yield a new exciting discovery.
People also enjoy the sustainability aspect of shopping at thrift stores. It's becoming increasingly popular to live sustainably, and thrift stores provide an affordable and eco-friendly way to do that. You can find some cool stuff that someone else might have discardied (or is it discarded? Discarded sounds more correct grammar-wise but discarding looks kinda fun), and give them a new lease of life!
Plus, the prices are definitely friendly on the wallet, which is a huge draw!
