Created a Spotify on my mobile using an Egypt VPN, then bought a 1 month Premium membership from mtcgame.com/ and applied it in the Spotify/redeem section - worked, so then bought a 12 month card and applied that, stacking successfully - £14.50. Seems the fastest/simplest/cheapest way to me (certainly the cheapest 12 month card option on that website).
For those that needed it, moved my Turkey Spotify to Egypt via spotmybackup.com/"}],"commentCount":5,"interactionStatistic":5,"articleSection":"Retailer Offers and Issues"}
