It's for my 6-year-old. I'm sure he'll think it's worth it.
No, I don't mean that it's not a good deal, or that your child won't enjoy it. I specifically mean that the money you would save from this bargain is not worth the amount of time and trouble you will have to spend acquiring it. Even if we chalk up a best-case scenario where there are plenty of these in stock and you have no trouble getting one, you will still be standing in line waiting for at least 3 hours, probably closer to 5. The time cost and discomfort you experience from that completely offsets the savings for the game.
I would consider the Skylander's pack to be a prime deal as well. But I WILL NOT wait in line at Toys R Us just for that. I would strongly recommend going elsewhere for that item. The only way I would brave Toys R Us for that is if there were seven or eight other deals I was also looking at getting at the same time.
