Consum on Camposol B & most other Spanish supermarkets will be closed all day on Good Friday, but they will open as normal on Saturday morning. If you need some supplies you could try Alan´s Supermarket in Camposol A, he opens every day of the week, but does close for Siesta between 2 & 4. Otherwise if you´re coming in from Murcia you could try Dos Mares as they advertise that they open every day of the year.
