Oops, sorry—not sure what happened to the Chase referral link, but I edited the post to add it. BofA isn’t running a referral program right now, so there isn’t a link for that card.
All of those flat-rate cards at the bottom should return 2% (or 1.8% in the case of Citizens, 1.5% in the case of Capital One, etc.) on payments through Facebook Fundraisers, given that their fixed cash back rates apply to all transactions. I can’t personally confirm that, not owning any of the 2% cards myself, but assuming they follow their policies, you should be just fine.
