It depends on the customer service reps at your store. I used to work at BBY, and I can tell you that official policy is that they don't price match package deals. They may be willing to make an exception, but it does have to be within 30 days. If they won't make an exception, you can always return it (again if within 30 days) and buy one at Gamestop or wherever.
