They have the standard Extreme III SDHC cards reduced to £29.97 which is not a good price as you can get that for £19.99, but amongst them are the Limited Edition 30 mb/s Class 6 cards for the same price. SKU Number is also the same 372725 I beleive.
NOTE: THE LINK SHOWS THE SLOWER CARD - DONT buy the slower card!

You can probably find this at Play and Amazon Merchants at similar prices but there might be P&P on top. (Play itself has it at £99.99) So this may not be the best deal by a few pence but it's good for the high street if you are passing. BUT DONT buy the slower card!!
