How much does Delta Airlines charge per suitcase on domestic flights?

Traveling from NY to Ft Myers Fl and from Orlando to NY how much does Delta charge per suitcase.

$25 or $30 for the first bag--it's also cheaper if you login at home and print your boarding pass/pay excess baggage charges BEFORE you get to the airport--you'll save $5 off whatever their fee is.

When I traveled last on Delta my carry on luggage was a pair of work boots, a coat, and a camera. I had to check the camera case and wear the coat otherwise it would have cost me $35. You are only allowed 1 personal item - my camera in this case - and the boots. By wearing the coat it was not considered a carry on.
$23 for the first suitcase and $32 for the second suitcase. If you check your bags in at Delta's counter once you arrive at the airport there is an additional $5 charge, but if you check in online 24 hours before your flight and prepay the baggage fees, you don't have to pay the extra $5.
$23 I think. Do not take a huge suitcase on the plane and clog up the overhead bins for everyone just because you are too cheap to pay $23. I am not saying you would, I am just annoyed by the idiots that do this.
