After what seems some confusion about the Banjo-Kazooie: Nuts & Bolts pre-order offer and Banjo-Kazooie XBLA giveaway, rare have clarified where you need to go to buy Nuts & Bolts and get the pre-order offer:
"For the blissfully unaware: it's an offer allowing those who pre-order Banjo-Kazooie: Nuts & Bolts (from certain retailers in certain territories - see below) to download the Xbox Live Arcade version of the original Banjo-Kazooie not only for free, but roughly two weeks in advance of its public release date. Which is not just awesome, but awesome in the voice of the surfer dude fish from SpongeBob SquarePants.
You'll get the free B-K download token on or near the time you pick up Nuts & Bolts, and for the period between the launch of the two games (Nuts & Bolts on November 11th/14th in US/Europe, B-K XBLA on November 26th), only N&B pre-order customers will be able to download and play B-K XBLA.
The price of Nuts & Bolts will vary by region (so it's no good shouting at us, disgruntled Brits) and Microsoft is still in the process of finalising all the territorial details, but here's what we know of participating countries and retailers so far...
FRANCE: Micromania and Game
SCANDINAVIA: Game and GameStop
Other countries known to be running the promotion but with no specific retailer info as yet: CANADA, JAPAN, IRELAND, GERMANY, AUSTRIA, BENELUX, SWITZERLAND, AUSTRALIA and NEW ZEALAND, probably not Uzbekistan or Narnia."
