Busters and mandp are currently punting Tourances (not the EXP's) out for 167 for a pair .........dunno if thats majorly lower than elsewhere as you will still need fitting if not doing it yourself
Last time i bought a pair was from Busters on an offer at 130 quid
Just paid £187 for a pair of EXP's from Pneus online and will be having them fitted at a local place in a couple of weeks. Fitting charge to loose wheels is very reasonable at £10 the pair with disposal being just a couple of £ more.
I've just changed my Tourances and got both fitted and balanced from National tyres on St Peters Way for £200. (They quoted £215 but I got the discount for taking the wheels off)
