Apartment complex recently started taking cards so I did a test with my AmEx and it's coding as Business Services. Spent some time with Google trying searches to come up with cards that offer a multiple for business services, but that's a tough phrase to weed through. Is there any known card that's currently available that offers a decent multiple for this general category, or a site that lists what cards are best used for which categories? I'd need to hit a value of about $0.028/point for it to be worth the fees, so I assume it will be rough.
