I looked at John Lewis for computer equipment and sometimes, dependning upon the time of year and when they are refitting, you can get excellent bargains.
However, at my local branch, John Lewis mainly supplies Sony equipment, this is OK but it is expensive. They are moving toward HP equipment at the moment and good deals can be had.
Personally, I'd never buy from John Lewis; here is the reason why and it is a true story:
I was in the Bluewater store and an elderly gentleman was looking at buying an entry level PC. In other words £300 - he wanted it to keep in touch with his grandkids and for a bit of word processing and Internet access.
The sales associate was totally incompetent - he didn't listen to the needs of the customer. I watched him - you could see the look of 'old fool easy profit' as John Lewis staff are on commission. The elderly gentleman was almost sold a £1500 machine and a useless £1000 aftercare policy.
I couldn't stand how the man was trying to be ripped off - I interrupted the conversation told the guy that he was being conned and promptly told him what he actually needed to spend, where he could get it from and some possible models.
Suffice to say I was asked to leave. However, I appreciate that every company needs to make a profit - but honesty is needed in business. Whenever I think of John Lewis - I think conmen. Sorry to anyone here who works for the company - but how that guy was treating the customer was diabolical.
Also - from what I could guage, John Lewis do not want to know if the thing breaks down after you have bought it. It is down to you to get in touch with the manufacturer yourself.
In short - avoid and go to another retailer - I'm sure people on this forum could give better advice on that one.
