Are you a My Best Buy Rewards member (free to join)? If not, you should be sure to join. Sometimes they have member only deals and members get perks such as points for every dollar you spend, receive exclusive member-only offers, and early access to their biggest sales and much more!
I have also found this membership helpful to keep track of purchases just in case I lose a receipt!
