I'm sure they are out of CTA range, but all is not lost if you have to pick up the cord from them. You can take the METRA north from Union Station to Libertyville, then a cab from the Libertyville station to the CDW store in Vernon Hills, if worst comes to worst. Libertyville and Vernon Hills are pretty close together. Here's hoping, though, the MI fellow comes through, and all this becomes academic!

(Maybe you ought to buy two cords from him, just to be safe? I seem to remember this happening to you once before, and I suspect it's only going to get harder to find replacement cords in the future.)
