We have lots of consignment shops here and I
love them! Most everything is very gently used...never worn out or ratty.
I found a Dooney & Bourke purse for $8 once at Goodwill! They obviously didn't know what they had. It looked like it had never been used. I was more excited about that than if I had bought it brand new.
I won't buy shoes at a consignment shop but I'll buy tops, jeans, dresses, accessories. There's nothing like getting several outfits for less than the price you'd pay for one at a department store.
