I found some nice shoes I liked on their website, It was free in-store collection, Standard delivery 3-5 days £3.99, Next day (delivered by Hermes) £4.99 and Premium next day (delivered by DPD) £5.99 on their website.
I went in-store and tried them on but I wanted a half size which they did not stock. The employee said that they can order them for collection within 3-5 days or pay £1 for next day delivery.
He found the shoes on the in-store touch screen and left me to fill out my details then pay at the tills.
May be useful for someone!
