But as general advice for anyone shopping around for rates, go the Deposit Best Buy threads on this site, use the "Thread Tools" menu at the top of the page to subscribe to the thread, and you will get e-mails whenever there are new posts.
Personally, I am only interested in the lump sums thread, and I am subscribed there. This mechanism works because Ciaran T religiously updates the thread with a notification any time any of the rates change, so let me take this opportunity to thank you very much indeed for this most valuable service.
