This is a pretty good idea to get around the difficulty of using AMEX cards for earning points. PerthHacks suggest buying Westfield gift cards which cost $1.95 for up to $995 credit if you want to use AMEX in smaller stores. More here http://perthhacks.blogspot.com/2010/12/how-to-shop-everywher…
Do you guys know of other ways to use AMEX more?
FYI not all stores in Westfield accept gift cards.
