Is it exclusive with Citi? Or any Visa will work for Costco now?
Exclusive with citi
Highly doubt that.The Citi issuance will be exclusive, not the acceptance.
VGC?
Stopped working for me several months ago.
I haven't tried recently, I guess I should try again.
Has never worked for me. But a workaround is to buy Costco Cash cards online with VGC. It's a hassle but works fine.
Will they accept Amex online (like they currently accept Visa/MC online)?
dont you have to register the VGX to your name/ss before you use it online?
