bigboss:Nope, they are legitimate. I've been to their shop in Glasgow. Give them a ring during their opening hours to enquire before you put your card details online.
I can vouch for bigboss and confirm they have a real shop in Sauchiehall Street, Glasgow. It has been there a few years apparently.
Having said that, I've emailed them several times asking which Samsung TVs they have in store for demo as I was interested in the 50" 850 plasma but had never seen it in the flesh. They've never bothered to reply to my mails or acknowledge my enquiry. I work in IT so hate it when a company has a wbesite with a customer enquiry facility which they don't bother to monitor. Phone them and see if a gruff Scottish accent answers!
I tried to pop in to the store, but I'm usually shopping in Glasgow on a Sunday, and they are always closed!
