I just checked GameStop’s website the other day and saw no mention of a pre-order gift for The Sims 2 Ikea Home Stuff. Now, Infinite Sims is reporting that they have one.
Now, when you pre-order The Sims™ 2 IKEA® Home Stuff * from GameStop, you’ll receive this exclusive downloadable NOMINELL chair as a special bonus! Offer good while supplies last.
Requires The Sims 2, The Sims 2 Double Deluxe, or The Sims 2 Holiday Edition for PC to play.
As for you Europeans, the official Sims 2 UK website has a page up which lists a few places that will offer gifts for pre-order.
