If you're trying to maximize your rewards and benefits with a specific retailer, picking up a store card is usually the route to take. You'll usually receive a great return when spending with the retailer and you'll receive exclusive benefits. The main drawback to store cards is that they have very high interest rates that can easily cancel out the rewards you've earned. If you don't plan on paying your full balance off every month, I do not recommend picking up a store card since the interest will cancel out any rewards you've earned.
