M&S 20% off - what to buy?

[Itscurtainsforyou]

Just seen that M&S have 20% today and tomorrow - I need some new knickers, anything else worth picking up?

TIA

Have they got anything nice? The last time I looked the clothes were not that great. The last pieces of sportswear I bought from there were poor quality.

These are really comfy despite their ludicrous height.
