Consider the same situation as before, but this time, John initially has $4 in his wallet instead of $19 and again he finds $5 on the street. After adding this to his wallet, he again discovers a forgotten envelope with $27.97 in it, which he also adds to his wallet. He then heads to the same collector's flea market. If he still purchases 17 vintage comic books, each at the new total amount in his wallet, how much does he spend this time on the comic books?
