Just a quick question, quite simple really. I'm going to Australia in a couple of months time for a month and plan on putting all my saved spending money onto my credit card, I figure this will be the best option. I'm currently saving into a demand deposit account and have a small-ish balance on my credit card. My question is whether I should put my savings each month onto my credit card rather than into my bank account so as to save on interest that I am paying each month. Are there any drawbacks/hidden charges to having your credit card in credit like that? The interest I am getting on my savings in my demand deposit account is not worth talking about so I wouldn't be bothered about not receiving that. Any ideas?
