The best flea markets Oslo

Fretex is a chain of 2nd hand shops that is actually owned by the Salvation Army of Norway, with a large thrift shop that is almost as clean as a new shop! It's hard to leave empty-handed! It is located near Majorstua, right next to a bookstore. If you're lucky, you'll be able to find some vintage thrift shops, super vintage cups that are usually quite expensive, like Porsgrunn porcelain, Royal Copenhagen, and all the typical Norwegian ceramic patterns that are quite sought after by antique dealers and enthusiasts!
