My Citi TY Preferred card just got an offer for an additional 4x for Paypal purchases up to 2500 bonus TYP, so $625. I don't use Paypal that much, generally just for the occasional Ebay purchase, but I don't have anything planned right now. I also don't have any upcoming purchases for any Paypal merchants that I've found online. What's the best MS opportunity other than paying a family member for "goods" or "services" and taking the 3% hit?
