Hi,
The two places you can try are Leroy Merlin & Carrefour.
Leroy Merlin is the equivalent of a very large B & Q.
Carrefour is next door to Leroy Merlin it is also very big.
You have to take the road that goes to Cartegna it take about 25 mins to get there from Terrazas.
Its a very big retail park with lots of other shops, its on the right hand side of the road you will see the big signs just before you take the turning, you have to cross 2 lanes to take the turning.
Hope this helps Clieve [ Clive & Eve ]
