Whilst browsing through this very site I've stumbled upon a few posts where people mention bargains purchased at the Itunes store.
A couple of examples
Citizen Steely Dan 66 tracks £7.99 (£36 on Amazon)
Gil Evans and Miles Davis complete Columbia studio recordings £6.99 for 127 tracks (£70.49 on Amazon)

Trouble is the bargains are a bugger to find. If only there was a way of pooling music lovers knowledge, and tracking them down...
So, found any bargains lately?
