Sorry I wasn't referring to $503.95 on every transaction. Actually I've never had a $503.95 purchase ever. Always tried to add a few items to the receipt or less than $500.

My point was to maintain a high average for $$$ per transaction. Put the highest bills on the MS cards. Let the small Netflix fills on other cards.

I think if your average transaction is $20-$30 chances of a fraud alert or manual review might be high if all of the sudden there is a purchase of $539.54. However if your $ per transaction averages $300 it might not be anything out of the ordinary since it would be your normal pattern of buying.

Just a thought.
