After trying several times to pay for an online shop, and getting a message saying "check you have available funds" (the implication being, I didnt), I panicked, and checked my online banking, plenty funds, I did a shop with asda, without any problems, I subsequently received an email from Iceland saying they were having problems with their online payment system, when I complained about their lack of customer service, they said I should have paid by PayPal!, if their system appears to be compromised, I would not give anymore information, there are plenty of other options out there, and I will not use Iceland again
