My usbank platinum visa would still cover it though? I'd just rather use this new card when I get it...but I guess I can use the visa on rentals.
Free-day or dollars-off coupons will definitely invalidate the Amex coverage; not sure about upgrade coupons. I think use of discount codes is OK.
I would not assume that your Visa would cover you if you use a free-day or dollars-off coupon. MasterCard is the only issuer I know of whose terms specifically allow use of such coupons as long as at least one full day's rental charges are charged to the card. If in doubt, contact your card issuer for clarification.
