As per the title I'm looking for 700x25c.
I started looking, but some places offer a discount for buying a pair, some have discount codes and others don't have them in stock so thought that someone is likely to have done the hard work recently (I just hope you don't mind sharing the wisdom) 😉
They were cheaper last week I think, but:

£31 but you'll pay postage?
Wiggle or ribble
Canyon were £25 each last week...I done got me some 😉
Sorry, not very helpful I know - there are often £60 bundle deals kicking about (with tubes) - previous ones I bought were from Merlin AFAIK.
Wiggle was cheapest I could find. Extra 10pc off at checkout IIRC.
They generally hover around the £30 (each) mark, sometimes you get a bundled pair with free tubes.
The other one to consider is the GP Force (rear) and Attack (front) pairing. Conti have released the mk3, so there may be some mk2 bargains
