I for one would strongly prefer that the identifier code within the url is changed so that the fact it is an affiliate-driven visitor is better disguised from the visitor's perspective.
Having the word "affiliate" in the url - twice - doesn't come close to meeting that aim.
I would respectfully suggest a change along the lines of the following instead:
http://www.phones2udirect.co.uk/Prod...f/LG_L1100.asp
http://www.phones2udirect.co.uk/prod...e/phones/a/af/
(ie subsitute "a" for "affiliate" and "af" for "affiliatefuture" / "
aw" for "affiliatewindow" respectively).
