Perhaps I do not understand rebidding as well as I thought I did, or perhaps they changed how it works. I just did the following: North Shore 40 +Deerfield 42 +Waukegan 44 +Lincolnshire 46 +Libertyville 48 +Gurnee 49 My assumption was that I could then continue trying different combinations (NS+W, NS+Lin, NS+Lib etc). So, I closed that browser tab and used your link to open a new one, and tried the following: North Shore + Waukegan 50 And got this message: "We were not able to process this request since our records indicate you have already made a request for this same trip."
