Bumped to the top of the page – great deal if you need them!
In this thread (must be registered to view) over at Cheapassgamer.com, a member has posted information about an upcoming 2-day sale at Toys R Us. It appears that they will have 50% off of select Sims PC games which include The Sims 2: Bon Voyage Expansion Pack for $14.99 (originally $29.99) and The Sims 2: H&M Fashion Stuff Expansion Pack for $9.99 (originally $19.99).
These are excellent prices, so I suggest if you need to do some christmas shopping for a Sims fan, check out Toys R Us on November 9th and 10th. They might also have deals going for all sims games, but I cannot confirm that at this time.
