I saw a thread over on the 5D Mk II for HD forum, saying that Currys were selling in store, Sandisk Extreme IV 8Gb CF cards for £24.99!!

I popped into my local shop today, and yes it's true, so I bought one.

It must be a mistake as they are selling the Extreme III 8Gb for £90!!

Grab yourself a bargain!!
