I could open a thrift store with all the doodads and unidentifiable farm implements left behind when the former owners left here. And throw in the stuff the pilgrims leave behind!
There are charity shops here, selling doilies and antimaccassars and tea-towels made by nuns. There are flea markets in bigger cities, usually on Sunday mornings. There are fair-trade shops selling goods made by rural folk in faraway lands, and there are classified ads for everything from used donkeys to downhill skis. But thrift stores? No.
In Spain (at least the part where I live), "thrift" means never, ever throwing away anything that might be useful someday. If you don´t have room for it, or it won´t fit, etc., you give it to your cousin or granny or friend, or you put it out in the barn. It wouldn´t occur to anyone to resell it, except perhaps to an antiques dealer.
