Interesting but the prices are well over Bitcoin exchange prices, the localbitcoin prices are all over the place, looks abit dodgy to me.
* I have used bitbargain for several purchases and sales myself and I can confirm it is legit.
It uses a straight forward transfer via 'UK Bank transfer' / 'Barclays PINGIT' / 'OKPAY' to name a few.
There are no hidden charges.
I used to use blockchain.info before they had to stop deposits. TBH although the rates may seem high on bitbargain, once you factor in commission etc. from other methods the price is actually quite good if you watch and wait you can get a 'bargain'.
I haven't had any experience with localbitcoins yet ... probably because I live in a small town .. I never met anyone here who's even heard of BTC yet.
give bitbargain a try (even a small amt) its very straight forward.
hope this helps.
