Whenever I've been to Warrington the "fashion" seems to be the most popular items and there are always several ladies loading up their trollies with multiple items. A lot of the stuff looks terrible - creased, some even with food stains down the front and for some reason most of the sizes are XLs and above. You can get some bargains though. I've bought Birkies for £9 and Clarks shoes for around the same price. I think I've only ever bought one clothing item from there - I'd accidentally jumped into the car and driven 200 miles without my coat - in February - (and no, I didn't just drive there to go to the outlet!) and managed to find a cashmere and wool blend coat for £4. No one had touched it because it was supposedly a Size 8, but QVC sizing is gynormous and even though I am a size 12-14, it fitted.
The best bargains I've had from the outlet have probably been the Furminators for around £4 each. I mostly go there for the craft stuff though.
