Ahhh £63 - very good 
Agree about different branches being completely worlds apart. I don't even go into primark that much but when I do, I can't handle the war zone frenetic piles of clothes everywhere vibe.
Birmingham and Oxford Street are prime examples. If you ever find yourselves in Coventry (god forbid :) ) by any chance, that's a really good one and never too busy so you can actually see what you're buying and navigate the shop without coming out in a stress rash.
