Does your local library membership include electronic magazines via an app like PressReader? Mine does and there are a ton of free magazines of all genres. In general they have the last three months worth of issues and it might help you find one you like before you buy a paper copy (if indeed that’s your style). Subscriptions are nearly always massively cheaper than buying in the shops.
I particularly enjoy Uncut, as being the best of all the music magazines IMHO. One of the only ones I read cover to cover is Linux Format. And I have a subscription to Retrogamer, but to be honest that’s not very good anymore and I won’t be renewing it.
