Best Buy will start taking pre-orders for the 8X and 920 tomorrow (10/21). The contract price of the 8x is 99.99 and 149.99 for the 920. Unfortunately, the only color options are Blue for the 8X and Black for the 920.
How do I know this? Well I do work in BB Mobile, and this is what showed up in our employee news. Yes, the 8X contract price is 50 dollars less than Walmart's.
All that is required is a 50 dollar deposit. So to be quite honest, I am not sure if the contract prices listed above reflect that of after the deposit or not. I read it a few times over, and it doesn't seem like that is the case.
