We live midway between Marbella and Fuengirola and yes very nice area to live in.
As for Amazon ES not sure if they would have what you are looking for. It is fairly new compared to the UK one and appear to have a very limited stock of anything.
We have only used it once to buy a small international adaptor and it took two weeks to arrive!
We tend to use Amazon UK who give us excellent serv ice normally 4 - 5 days delivery and very reasonable postage charges provided it is Amazo. Who are the sellers and not being sold by another company.
