I tried to order an ultegra sl rear mech yesterday on cycle store site yesterday at £40 and a few pence. Their website wouldn't let me get past the dispatch address section, came up with 'pace cannot be displayed' and I e-mailed them about the problem and got a response to say they had plenty of orders that day. So I said I would try again today. So I just did - the mech is now over £70.
Now that's some price hike.
