What a load of rubbish.
Why stop at CRC, why not get onto Boeing and tell them to stop selling planes to Ryanair and Easyjet because they sell their tickets too cheap? Why not get onto book publishers and tell them to stop selling books to Amazon because they’re too cheap???
I use CRC for one major reason, despite living in London, I don’t have an LBS, at least not within a reasonable distance, the nearest to me is probably 15 miles away, so CRC it is.
