Irvine is there a Costco anywhere near you? I know some places like in Wisconsin where there is no Costco. My dad was telling me is that they are located up north where a lot of people live.
Did you know at 1 time Costco only took Discover? What makes you want to get there card?
My parents have this card and I think this is a stupid card. I guess if you live close enough that's 1 thing, but if you live somewhere, where there are no Costcos or you have to relocate from Boston Mass to Portland Oregon, this is a dumb card.
It is always better to use your own card. Since you're in Utah I don't think your going to be relocating anytime soon.
I'm not a Costco member BUT IF I WAS I would use my own personal card. I would use my green card.
Irvine out where you live do you have a BJS? Do you know if they give 1 day passes? Costco doesn't. You know that BJs accepts competitors coupons, Costco doesn't. And with BJS you can use your Discover more or Citibank diamond card. At Costco you can only use your Zync card.
I would choose the Blue Cash card
over the junky aqua Costco card in a heartbeat.
