Cheapest I can see it for by £10, and cheaper than the logical alternative, the C300 128GB. Seems like a great deal to me.
I know it's been about this cheap before (and will be this cheap again in the future), but currently this is notably lower than it is anywhere else and thus a good deal.
(Also: this is my first deal!! So go easy on me. What? I thought it was a HUKD tradition to write that for your first deal...)
NOTE: This will take you to the product page showing you the normal price, click 'today only' on the left and scroll down a bit for the lower price. Click 'buy' to put it in your basket at that price, don't go to the product page.
