yes anyone who doesnt know where to buy anything, then try the wonderful 9 floors department store El Corte Inles in lisbon..the metro station is right underneath....they have a good a selection as Harrods or selfridges..and for a small fee can deliver to algarve.

also the colombo centre in lisbon has 400 shops and 45 resturants with firms like Habitat there who like el cort ingles also deliver and will assemble any furniture you buy
