Yes, you can now pay your Argos card bill online at www.myargoscard.co.uk. All you need to do is register and then you can log on and view your account summary, make a payment, and do a host of other useful things as well.
...unfortunately it doesnt allow to people to log on correctly so is practically useless as a payment site!.
Other people asked questions on various topics, and are still waiting for answer. Would be great if you can take a sec and answer them
