Just be aware that, when your card expires, Nationwide will not send the replacement to you (not in Phils, anyway). For the last six months I've not been able to use a card on my Nationwide account.
Many other banks will send cards to Phils - I have received BoS and MBNA cards since I've been here. I'm not sure why Nationwide have this petty restriction. Since I no longer have an address in UK, the only way I can obtain my card is to pay a visit to my 'nearest' branch. Now, who can tell me where my nearest Nationwide branch is?
