I have about 90 coins that I'd like to sell via bank transfer or Pingit. There are also 3 other sellers with coins in the system currently. The offers' prices are generally around Mt.Gox+2%.
Transactions are complete in under 10 minutes.
The page to start a transaction with me:
http://bit.ly/bitcoin-uk (you can change the 10 BTC part to another amount, 10 is just the default)
If:
1) I'm not online
2) You want to check if anyone else has better prices
3) I don't have enough in escrow
...then just go to the buy page to see all of the offers:
https://bitbargain.co.uk/buyWhen you click 'start transaction' I get a text message and have 100 seconds to accept the deal.
(What to expect - the price and seller name is just an example)
