Its my right as a consumer.
You may well need to buy a size up, buying online means you could spend a while finding a pair that suits, and time and possibly money returning them. Or you could go to Evans, find a pair, use your smart phone to find a cheaper price and then get a price match at the till. Evans have a list of match competitors on their site. Other chains have a similar policy
As per the ad "PLEASE NOTE THESE PEDALS COME WITHOUT CLEATS ", so once you've factored in buying the cleats (which they've probably taken out of the pedal box) separately, CRC is cheaper.
They usually do every time, in my experience... and if not they come a bloody close secondCRC WIN!!
