this might be a dumb question, but we're looking to make a big purchase on costco soon, and trying to max out our possible points/miles from it.
Checked on evreward.com, and saw that amex rewards programs can get 3 miles/$ (http://evreward.com/store/go/3464
), but I've never seen any indication on either card I have (amex plat and PR gold) that it would get any bonus miles.
Any idea where that 3 pts/$ comes from, or any tips to max out our harvest? Thanks in advance!
