Thanks for the advice guys.
I was just about to pull the trigger on a mid-grey flannel Canali jacket. Yoox UK was giving me a total of £214.
After looking through some recent posts, I looked on the Spanish version of the site, where the same jacket was around £140 with free delivery!
Looks like my grandma is going to be my new proxy (I tried shipping to a UK address but the order was automatically cancelled).
