There are couple of things you should be aware of unless they have changed the process since last March.
You may need to watch your card limits. Each charge goes to your card as a pending charge when you make it. THEN, at about 2:00 a.m. they will consolidate the charges for the day and the consolidated charge will show up on your card as a pending charge. So if you make $200 charges during the day they will be consolidated into a single charge, and when you get up the next morning your card will have $400 in pending charges.
Also, I have alerts turned on for my card, so I was getting an alert at 2:00 a.m. every morning when they posted the consolidated charge. I finally turned if off after a couple of days.
