It would appear that it is only Visa & Mastercard, which is a bit of a shame.
Luckily I've got the MBNA Amex thingy which includes a Visa for places that don't take Amex - so far the only place I've found that doesn't take it though is B&Q.
Probably worth getting another MBNA card with the Amex/Visa if you don't already. Makes that fee a bit more bearable
