Ferreteria Lopez on Mojacar Playa they have loads or if you have a car then you have to go to Carrefour in Almeria alot more choice and cheaper, we bought ours there,its a nice drive. I will give you directions if you want ,its easy. of course being a large store they sell everything from bikes to bedding from computers to food, very good and nowhere as far as Murcia
hopes this helps
