I was looking around for a way to make online purchases or sign card in usd for ages,
I have some usd from my stocks and I always thought it’s stupid to Buy stuff in usd and pay in sgd.
I finally found that Citibank debit master card can be linked to my usd checking account and any purchases made in usd on that card will deduct usd directly with zero exchange fee. I was asking Citibank for ages for a usd credit card and they always told me don’t have.....
Hopefully this info is useful to somebody.
