I received the same survey too yesterday.
I've been somewhat unhappy with the card benefits in the last year or 2,
and put that in the feedback:
poor recognition in store, lack of bonus points offers, fewer VIP events etc.
Earning rate in store isn't much to shout about either,
7 points per dollar for DJ purchases should be 10 points per dollar, IMO.
The possible changes are an improvement, but not amazing.
One possible benefit is $40 birthday gift to spend in store - really ???
Another is priority service at cash register - no need to queue to pay.
That would be useful at sale time, I guess.
The one big let down is how the points redeeming structure is not aligned with Amex MR,
ie at the same rates. (yes I know some ppl like the SPG rate...)
If David Jones could do that, the card would be spectacular.
