Data points:

May spending earned cash back, of course, but June Tracker bar presents difficulty.

47% Everyday, 53% Elsewhere. Reality is that over 85% was CVS.

I feel like the young people in that movie who received the note saying I Know What You Did Last Summer. The real horror is in the suspense and in trying to figure it out.

Possible conclusions from the AMEX I Know What You Did Last Month tracker bar:

1. Some of the registers provide detailed data allowing AMEX to adjust the reward from 5% to 0%/1%. We will never be able to figure out which register to use, so the card might be a 2% - 2.5% return card, which is still a good deal.

2. Sometime in mid-June, the entire detailed tracking system came into place, which means that from that point forward, the rewards are 0% or 1%.

Is anyone seeing a tracker bar from the June online system that gives 5% for all CVS purchases?
