I was always used to $0.20 deltas between 87 and 91, though I don't think that's been very typical for a while now. I, too, noticed a very large delta the last time I filled up my SC (which requires 91) - I don't remember what it was, but it was a lot more than $0.40. Just gotta suck it up!
There is very, very little money in selling gas itself, particularly the 87 that most people use. Gas stations make their money off of everything else, but there probably is more margin in higher-octane gas than in 87.
