Thanks for that wonderful insight.
It's totally pointless exercise. I'd be very interested in buying but I'm not going to gift an etailer £100 for a few weeks on the promise of a card I know little about, least of all the actual price. How do you know they'll be competitive? If they're not you'll have to go to the hassle of calling up for a refund and waiting the usual 5+ days.
100+ Pre-order on this exact scheme seem to indicate it is FAR from a pointless exercise.
Go troll elsewhere.
