Stop in for a cup of coffee

I am trying to figure out my paint cost. BAPS quoted me 45.90/qt on SS PPG JEB. That's what I used on bay and jambs. It gets cut 4:1:1 IIRC. judging by previous results I figure I would need 3 coats using 2-3 qts. Not sure what gets added to the Basecoat. That's 57.28/qt. But if I go that route I then need probably a gallon of clear which is another bill... I don't need a 'show' finish. If I could get a good clean shoot with SS I would be happy.
that's cheap.... the paint im looking at is 4 times that per quart.....
