I have converted my boyfriend as well.
He likes Diesal jeans and they are £100-£150 in the shops. He has brought 2 jeans now for around £15 each.
This weekend he won some D&G jeans for £15.00 and there RRP is £150.
I do agree what you have to know what you are looking for as you can't really take it back like you can in the shops.
