Music Magazine Task - Price and Frequency of Magazine Publication

I have decided to publish my magazine on a monthly basis at the price of £4.00. I have done this because I feel that it would be more benficial to the readers of the specified publication to pay £4.00 once a month to recieve a fairly large magazine rather than paying £2.50/£3.00 a week for a magazine that is only around 60-75 pages thick like the magazines Kerrang! or NME.
