Magazine - Costs

A single Kerrang issue usually sells in the UK for £2.20 and a NME magazine costing the same. Therefore I know that these magazines are affordable to my target audience as the age range is around about the same. I've decided that my price will need to be cheaper because it is mainly orientated around smaller and up-coming bands, so the target audience won't want to spend the same amount of money on a magazine that has bands that could be very unknown. I was thinking that the £1.60-£1.80 mark would be an effective amount because this will be affordable for students and cheaper than the two named above.
