Discover It Paypal Quarterly 5% Bonus
 

From July 1-Sept. 30, Discover It cardholders can get 5% back (cap $1,500) on paypal transactions including friends and family (card must be in Paypal wallet). I have not seen Paypal on Disc. bonuses in previous years. Anyhoo, if you are looking to churn a credit card this summer to make a big baseball card purchase, this is a good place to start.
