Mine had the decals, they have recently pulled them all off, thinking that contactless is coming soon. On the Costco reddit page it has been working at some warehouses already, as well as a QR Code membership card for scanning at the pump.
I was there getting gas today, and they have removed the decals from the pumps at my location. I asked the attendant about it, and he said "you'll be able to pay with it soon." He also did say that the scanner just below it is for mobile membership cards, which are also "rolling out soon." I'll take this with a huge grain of salt, considering all the misinformation I've gotten from them about this already.
