Bset place to buy the piano exam pieces, scales book and sight reading pack with CD?

I am about to buy the Grade 8 exam pieces, scales&arpeggios and sight reading books along with the cd, but have been toiling through various sites without much luck. Last year I got a really good deal on the whole package-around 30.00 with free postage but I can't remember where I ordered from. Anyone have any links to reasonably priced places? It is so annoying as there are no music shops locally and I don't want to go into London, so I have to shop online, which adds the cost of postage onto the price. Really dont want to wait too long to get these books. Ideas? Tips?
