Not on a product with a ~7% margin.
For what It's worth, I once tried to spend £3k with PC World. Not only would they not offer any kind of deal, they wouldn't even let me enter their store with my.rucksack on.
You do look dodgy as fuck though, I wouldn't even let you past the front door of my store if I had one :p
That's OK, Manthrob has taught me the many benefits of the back door.
