Hi Jamie,
Depends what you are after?
We got our washing Machine and Fridge Freezer from Media Markt in Murcia, they delivered and installed for a small fee.
They also do kettles, toasters, TV's etc etc.
You Could try Al Campo supermarket too, they have a decent selection of electricals, not sure about delivery though.
Both stores are near IKEA, ( just on opposite sides of the motorway)
Good luck
