Went to one in Swindon couple of weeks ago, third time I've been.
For once I got there early enough to not have to join the queue outside. It's civil though people do tend to grab anything that there's an outside chance they might buy before retreating to the edge of the hall & rationalizing their basket.
The stock comprised a huge amount of items that had been labelled faulty - more than I ever recall in the past. Whilst some of the faults were dirty marks that would have probably cleaned off, I did see a lady pick up a pair of boy's trousers that had a horrendous rip at the front top of leg that wouldn't't be salvageable. Other faults were sizing issues where the length or width differed by 2-5 cm from what had been advertised.
