Curious about it as well. I know they can if they want to. My USB Altitude was shut down even though it was all groceries and drug stores mixed with a ton of "organic" spend. The level 3 reporting or whatever surely gives a way for the CC companies to see purchases if they care enough. With the new AM3X HH A$end cards, I'm wondering if there are any DP's on getting signup bonuses through buying GC's at groceries stores. Any references to such DP's would be appreciated.
