Applied and received USD Visa for myself and sub card for one of my parents
Signed up 6X as Overseas Spending for this parent
Applied for Paypal account in parent's name
Paid US$10 to myself
Got 2RC posted yesterday
Therefore 6X applies to USD card as well (US$10 / US$30 per RC x 6 = 2RC as received)
