Something to keep in mind with this pre-order deal.
Most credit cards offer some kind of warranty. My american express for instance extends the manufacturers warranty by 1 year, the first three months is protected by theft and accidental damage protection insurance.
The catch? The entire purchase must be made on the card. So if you put $50 down as a pre-order, and they give you a gift card, and you return to purchase it using the gift card, essentially you are only putting $750 of the $800 on your card and thus the extended warranty / damage protection aren't eligible.
I've used the 90 days damage protection and the extended warranty. They issued a full refund to my card both times.
Just something else to consider with the pre-order deal.
