I received that email too and bought jeggings, a white shirt and white tee-shirt in the last sale which I'm very happy with. Quality material. Another poster mentioned buying slippers from M&S. I bought 3 pairs of shoes last year, real suede ankle-strap heels for 1/3 price in sale. You can guess that I usually shop in their sales.
I prefer Zara, River Island, Mango and my all time favourite, Primark, however, I do find some nice pieces in John Lewis including a long grey Bruce Oldfield trench which is wonderful.
The photo shows Primark suede look slippers bought 3 years ago. Never needed washing and with sturdy soles. A fab buy at £4. I also bought them in 2 other colours.
