Advertised a competitive price so I went with them. Turns out the don't have the item in stock and can't make a profit selling it to me at the price they advertised it, so they cancelled the order.
This means I've missed the cashback promotion that was being run, despite calling them up before placing the order in the hope of ensuring all would go smoothly.
So I'm now $200 poorer and strongly recommend going with a different site, perhaps one that doesn't put up prices it won't actually honor.
