If you come out of the back of the hotel, and turn left across the bridge and turn left again, there a few small complexes and i think there is one that sells papers etc. If not just walk up the road just past the golf club, and turn right there is a supermercardo in the green golf complex. Otherwise you can walk further along to the Faro 2 cc. There are complexes at the back entrance of the hotel so give them a try, most got little supermarkets inside them.
