A couple of months ago I used a Tech Head card on Amazon Australia.
Now I wanted to use a different Tech Head card there, but when I try to add it as a payment method on Amazon it gives the error message "Incorrect card details or card not supported."
Has anyone been able to use one of those cards on Amazon recently?
I strongly suspect Special has blocked Amazon AU as a merchant on the Tech Head gift card.
A whole bunch of AMEX cardholders were using Tech Head gift cards at Amazon AU earlier this month when a Special cashback offer went live, and then it stopped working. The first report of transactions at Amazon AU being declined was late on 10 April, and if you scroll through that deal, you will see many more similar reports.
