Unfortunately, this deal is no longer valid

Not sure if everyone here knows about this, but it seems that you can transfer money from your Barclaycard credit account to your current account. I don't think other credit card companies offer such feature. As the screenshot in comment 1 shows, it's 0% interest rate, but 1.9% or £1.90 transfer fee applies, Minimum transfer is £100. I'm not going to use it myself, but thought someone out there might find it useful ...
