As I don't know of any card that currently gives me 1.5 points per dollar on grocery shopping, and as my Platinum Edge card is effectively free given the Travel Credit, I'll be holding on to it and collecting 1.5 current points per dollar at grocery stores. Though I'll get better value from my Qantas Money Mastercard or Jetstar Mastercard anywhere where my Platinum Edge card currently only earns a point a dollar, as that will become effectively half a point per dollar.
I've been using up my Member Reward points booking hotel rooms for this year's trip. I had a stroke of luck the other night, when I'd accumulated enough points to book another room for a night in Lisbon. I cancelled my 7 night booking in Lisbon, bought the first night with the Member Reward points at about the same price as Booking.com had for it, then rebooked the remaining 6 nights at the same hotel at Booking.com. There was some Genius discount going on that day, and I saved around $200 on the last six nights relative to my previous booking. I most probably wouldn't have checked, had I not been trying to use the Member Reward points up.

Renato
