They are saying they have hi-fi rush for £1.20, but if you order it they claim its a pricing error and asks you to choose a refund option of refunding back to your bank etc or refunding to their site as credit.
It happened to me near 12 hours ago and around a hour ago I see the price is back on this site from them. If it was an "error" they wouldn't be reposting it for the same price.
Seems like they are just hoping people will choose the site credit option...
