If they can beat less then $8 for 50 CV bolts then it just might have been worth a trip. McMaster-Carr sells a 50 pack of regular alloy steel 12.9 M8 bolts for $7.38 or a 50 pack of the same size but in blue-alloy steel (supposedly rust resistent) for $12.07.
I splurged and went with the blue alloy steel option
