There are plenty of bargains to be had if you’re a British digital music consumer at the moment. Tesco is selling the MP3 version of the new U2 album for £3.97 for example, in a week-long deal that almost rivals the $3.99 Amazon was selling it for in the US earlier this week. Meanwhile, Amazon is selling The Prodigy’s new album for £3, and ten of the most popular chart singles for £0.29 each. “We believe that offering these ten chart-topping tracks for only 29p, we will encourage even more people to experience the Amazon MP3 store,” says Amazon’s Julian Monaghan. Yes, but at what price in terms of consumer perceptions – will they expect all tracks to be that price?
