We went shopping last Saturday in an area of town I haven´t been to for a long time ! low and behold there was one of the largest Stockholms Stadsmission shops there. Must have been at least 800 sq m of clothes and brick a brack. I bought a v-neck, a black leather handbag, a shawl, a blouse (which I was really pleased with since I have seen similar ones for about 1000 sek my price 40 sek $4) and a lovely 100% cotton dress for Summer. The total price for two bags of clothes came in at 250 sek $ 25. SO this is now my absolute favourite second-hand store.
My second favourite is of course Myrorna. I have bought some lovely handbags here !
Röda Korset in the south of Stockholm is great too, I remember buying a samsonite suitcase for 5o sek $5 there which has had a lot of use over the years. I also bought my TOD handbag there for an amazing price.
Last but not least is Möjligheternas Hus in Skarpnäck Stockholm. It´s amazing prices and high quality furniture is a great place to find bargains. I also donate a lot of items to them for a good cause.
