La Ermita supermarket on the Jesus Pobre road is a 2 minute drive from La Casita. It's functional rather than flash, but stocks all the basics. The butcher is superb, speaks perfect English and is a real character. His meat is outstanding and as they're local we do our best to support them as much as possible.
