I realize you don't like the terms being changed (I don't like delta...they killed NW) but at the same time seriously how hard is it to make 5 debit purchases.
If you are one of the old ladies holding everyone up at the grocery store writing checks.....I hate to be the one to tell you but....psssst debit cards do the exact same thing, only simpler.
As much as I like the, "one banana at a time," suggestion, I'm currently netting 10-14% cash back (well TYP, so Expedia cash) on my PPE card, which runs through the end of Q2, so I've been trying to use it exclusively.
I actually don't need a Chase account; the only remaining thing I like about Chase is that they have lots of grocery store branches around here (i.e. can often kill two birds with one stone/errand).
