I would never deal with Sound & Vision again, or their other shop digitaldirect. They took payment from me for a TV last year, rang to confirm a delivery date and then simply failed to show. I had stopped in all day waiting for them, and I wasn't happy.
I subsequently found out that the TV was never in stock and I should have been called to cancel. Despite a number of promises of stock arriving, it became obvious that they couldn't supply the TV and I cancelled the order - I then had to contact them several times to get them to refund my money. In all, they had my money for over a month.
They're probably OK if the stuff is actually in stock - but then again, their sales team confirmed that the TV I ordered was 'in stock'...
I then went to empire direct, which is another story!
