I have just tested this.
I copied you code to a .txt file on my local pc and renamed it afterwards to a .htm file so i would get a link when i open it.
Once i click that link i'll go to the ebay store (front page). If i manually copy your link into my browser i'm redirected to the same page on ebay (front page).
This mean that the campaign no longer exists or it is just for ebays front page.
Just take the HREF portion of the link http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=1&pub=5575033840&toolid=10001&campid=5337240729&customid=&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg
