I see that after the auction house closure, it has now opened as "Dawlish Emporium", buying and selling second hand goods.
Had a quick look, seems a bit pricey, maybe they're open to negotion though?
Ellies Attic seems a better option
Yeah Ellie's Attic is great (it's on Shutterton Industrial Estate. Turn into the estate, then turn right by Dawlish Carpets. Ellie's Attic is on your left. They've just expanded into the premises next door so much stuff do they have).
