Spotted this a moment ago. Cheapest I know of since;
GAME: £19.99 (Online) or £24.99 (Instore)
Unfortunately the 10% Discount for Students is excluded from this item.
"Note: This product is excluded from our Student Discount. "
I have one of these myself that I purchased from GAME for £24.99!
They're fantastic and much easier and practical than a full-size USB keyboard. Work with some mobile phones, too!
