MagicTheGathering/WhereToBuy

NoNoNoNo. Just don't. It is a slippery slippery slope.
For example, AlexChurchill has spent literally over a thousand pounds on the game. It's bad. Go and get into FootBall or PuertoRico instead.
But if you must buy MagicTheGathering cards, then see below for where best to...

In Cambridge

Where, in Cambridge, can I get Magic cards at a reasonable price? I miss GamesAndPuzzles - where else sells them? --Requiem

: The answer these days is InnerSanctumCollectibles?, CB2 8NX , www.innersanctumcollectibles.co.uk. --AC

Online

http://www.blackborder.com: they're likely to have among the best prices you'll find outside of eBay, because they survey 15-20 good online card retailers every few hours and match their prices to the best out of them. AlexChurchill has bought from them a couple of times with no hitch.
eBay: As trustworthy as the person you buy from. Which varies a lot. AlexChurchill has had mostly fairly good results from British, American, Canadian and Australian sellers. Look around for those with cheap shipping to your country. He's had at least one bad experience from manaleak.com and two different German sellers.
Other websites that AC's had good experiences with are millionpointfireball, wagicalplace, and others.
FlameRider recommends http://www.psi-soft.co.uk .
ThePants999 uses http://iguk.co.uk for boosters as they do boosters at Ł2.39 or 3 for Ł6.49 and have free delivery.

I know of one place in Canterbury that sells them a bit cheaper than mentioned above. Westgate Games has boosters for Ł2.40, and tournament packs for... Ł6.99, I think. Probably not any real useto most people, but it is cheaper than most places. --FR
