All the MAC Pro products and US prices are on
http://www.macpro.com, but as for the UK prices, i'm not too sure of all of them. I know that the specktra international price list has some UK prices but not for the blushcreme
here is the link

If you're desperate, maybe try calling the Pro store in Soho and ask them for an exact price on the Blushcreme pro pan, I know the eyeshadow pans are £7 so I would assume the Blush pans would be around the £11 mark, but thats just a guess...
