You may apply for the My Best Buy Credit Card in-store or online. You stand to benefit by getting this card if you plan to make purchases through Best Buy, all the more so because it comes with no annual fees.
The best way to maximize the rewards you may earn through this card is to use it within the first 14 days, as this lets you earn double the rewards. After those fourteen days, all purchases earn 5% back in rewards (or 2.5X points per dollar).
An alternative to earning rewards is opting to pay for your purchases over time using the card's no-interest financing plans based on various categories and the amount you spend.
