Those chaps at Amazon

are jolly nice. I ordered the Creative Zen Vision W 30gb mp3 player from them for £145.55 a few days ago (+ student discount and free pnp) but then yesterday the price went down to £139.99. Emailed them and within an hour I got refund for the difference (£5.56). So in total I got an mp3 player which has more features, better compatibility and higher visual and sound quality than an ipod, for only £132.72.

*thrust* woooooof
