A lot of deals posted here require you to put in your credit card even for a free trial subscription (or similar).
So I've found two options, either buy a visa giftcard (like those available from Aus post and woollies), or use a virtual credit card service, which allows you to generate cards and put a fixed amount onto them (like $20).
For visa gift cards, what are the best ones available, with the longest expiry dates, and the lowest purchase/activation fee?
For virtual credit cards, what are the best companies to go with, again with the lowest overall fees?
Cheers!
Divipay. Free but have to top up at least $5 which you can use. No fees for foreign transactions.
