price and publishing

i have considered the prices of other music magazines and how they change their prices with different publishing dates for example metal hammer charge around £4.00 for their magazine but it is published monthly where as kerrang publish theirs every week and only charge £2.20 for their magazine. i am also going to publish this magazine weekly so it would be wise to put the price around £2.20 . this is also a sensible price because looking at kerrang and how many copies they sell shows that my target audience should be able to afford it and want to buy it every week. publishing the magazine weekly is about as often enough as it needs to be published because this gives chance for the music industry to get enough news and updates to be published in the magazine and if i published it any more often the magazine would end up to thin and it wouldn't make enough money , but on the other hand if i published it less often e.g. monthly , i would have to charge more money for it and some readers may miss issues.
