Magazine Prices

I have researched the prices of 3 music magazines that have influenced my magazine the most in order to get an idea of the price my magazine would be.
Kerang!
NME is the cheapest magazine and costs £2.10
Kerang! magazine costs £2.20
Q magazine is the most expensive magazine and costs £3.90

I have decided that my magazine is going to be at a price of £3.30 as this is approximately the average of the above magazine costs.
