I pre-ordered FIFA for $69 the other night during the boosted 10% CR offer, predicting that Amazon would match the Gamesmen's deal (which would make it cheaper overall).
Two days later, and the price was still $69 so, like the OzBargainer I am, I contacted Amazon just then asking if they would match the Gamesmen's price on eBay and the price was changed just minutes after.
I asked if they would also match the additional eBay 5% discount (I cited that they did the same thing for Spiderman from the exact same seller using the exact same eBay code) however he said that couldn't be done BUT he instead applied an additional $4 discount to my order, which brought it down to $62. As such, perhaps you should try contacting them to see if you can get any additional discount.
As such, the effective price of this can be brought down to $55.80 if you took advantage of 10% CB, or even $58.30 if use the standard 6% CB rate.
EDIT: A key point I forgot to add is that using expedited shipping (free for Prime) will guarantee it arrives by release date, which is something the Gamesmen can't guarantee (and is already highly unlikely) as they will only be posting it out just 1 day before release whereas Amazon will send it at least 2 days before. The Gamesmen rep confirmed that even if you pay extra for Express shipping, they still can't guarantee it would arrive on release date, which is quite a drawback for those that play Ultimate Team.
Not a bad price for a new release
