To answer my own question, the largest Exodus 580L is reduced from £450 to £250 but in-store only and with very limited stock remaining. Picked up one yesterday :)
20% off on ebay halfords
Gutted I missed the extra 10%, that's probably a deal breaker, anyone made use of the Exodus 470L Roof Box Gloss Black. Is that a good buy ?
I already have a 400l box why do I want another one at only 250l. Could be handy but should resist.
My phone was dying so I thought I would highlight the codes existence even if I didn't provide it (embarrassed)
