I have been a Platinum member for a while. Have also held the gold in the past.That's not an issue for us. The Executive Membership which gives another 2% on Costco purchases, including Costco travel, rebates us almost enough to cover the membership. With the 5% on gas, 3% on travel, 3% on dining, and the fact that we are about a mile from Costco it works for us, YMMV.
I keep trying but I cant seem to justify the $695+ annual fee. I did get an AMEX Platinum welcome bonus offer of 175,000 miles and that may tip the scales but I don't like the coupons. If it feels like work, I'm not interested.
With a new price increase coming, I'm giving the green card a serious look. 3x travel on everything including cruises, hotels, etc. seems like easy one stop shopping... 3x dining is also good.
sam's card for the gas and groceries.
If we weren't a disney family I would put all my spend on WOH credit card.
