Do all cards have a minimum price difference before you can claim a price difference on an item purchased with them? With BankWest, the price has to have dropped by a minimum of $75, and from memory, the lower price has to be in PRINT.
Price Protection and travel insurance were the two reasons we got a platinum card, and it seems their travel insurance (including hire car excess cover) doesn't really apply for the vast majority of our travel anyway - ie, domestic. We ended up taking out an annual travel insurance policy through Aust Post, so price protection is the thing that I really need to do some homework on at the moment.
yes afaik
bankwest has interstate flight inconvenience insurance, anz has free domestic travel insurance for seniors, anz/citibank/others cover rental car excess
