Thanks kwildnj for the providing the steps.
I am also trying to book my Amtrak tickets but for Sunday from Wilmington to EWR. But its so expensive on sunday I get the lowest fare $62 in the early morning or $86 at around noon, which is early but still fine with me the rest is all above $100 one way. coming back is $46 which is fine.
I was wondering if any one has any codes to share so I can get that price reduced.
