I see it as dishonest and exploitative. The error was reported as a glitch early on, and yet folk flocked to get, effectively, something for nothing. It may seem like a means of putting one up Halfords, but perhaps people could take time out and reflect on what it means. The glitch was put on HUKD. Perhaps a dozen cycle chatters managed to ( who used the term "loot"?) take advantage, including at least one whose order went into thousands of pounds, so multiply this by literally hundreds, if not thousands of people all doing much the same. I liken it to the rioters of a couple of years ago who went into town knowing the stores were all being smashed up and running away with armfuls of designer gear.
Halfords may be crap in some people's eyes, but they sell a large number of good value bikes to a lot of people. This forum is full of people willing to criticise, but think about it. Many buyers don't know what they want and haven't researched bikes before going in. Their criteria may even be the colour of the basket on the front, and staff do their best, given their knowledge and experience to match what a customer needs with a decent bike. This is open to criticism, and I for one wish they would take a long hard look at their business model, but I still go in on a Sunday when i need a gear cable or a set of bolts. How can they hope to improve their business if they are trying to make up for losses of possibly tens,or even hundreds of thousands of pounds lost to looters?
This comes across as bitterness to be honest. I bet you didn't sit and make a concious decision not to use it.
Halfords could have quite legally have sent us all an email apologising for the error and cancelled the orders. They chose not to.
