Thrift shops are selling used goods for prices similar to fast fashion. Many don't enjoy this experience as it no longer feels satisfying to get a bargain.
When I lived in Toronto, my favorite place to find clothes was the thrift shop. Especially when my first child was born. Often I was able to get like-new looking brand-name clothes for a fifth of the price, which was especially great for children's clothing that are only worn a handful of times before the baby no longer fits.
