If you are a frequent eBay shopper, you may choose eBay credit card, but keep in mind that this card gives 2x points on PayPal and eBay purchases and only 1x point on all other purchases. If you want to earn more rewards, you can choose from cash back credit cards that are not affiliated with a store. For example, consider the Discover it® Cash Back credit card. This card offers general 1% cash back on all purchases and 5% cash back on up to $1,500 in purchases when you activate. Every quarter you should sign up for 5% cash back bonus, otherwise you won’t be eligible for it. All the cash back earned at the end of your first year will be matched automatically (if you are a new cardmember). For example, if you earn $150, you will receive $300.
